1 Introduction to the Storage Subsystem The storage subsystem allows you to use SCF to configure and manage storage devices online.
Introduction to the Storage Subsystem Manager Processes Manager Processes Storage Subsystem Manager ($ZZSTO) The $ZZSTO storage subsystem manager process is a generic process that uses SCF to perform persistent configuration and management. That is, when you use SCF to change the system configuration database, the changes survive a system load. After you configure storage subsystem objects online, $ZZSTO maintains this configuration information in the system configuration database ($SYSTEM.ZSYSCONF.
Configuration Overview Introduction to the Storage Subsystem SMF uses these object types in the storage subsystem: Object Type Description Section DISK Virtual disk process Section 10, Configuring and Managing Virtual Disks MON SMF monitor process $ZSMS Section 4, Configuring and Managing the SMF Master Process POOL Storage pool process created from multiple magnetic disks Section 9, Configuring and Managing Storage Pools for Magnetic Disks Configuration Overview To Make Configuration Changes
Introduction to the Storage Subsystem Using OBEYFORM to Create an SCF Command File Comparing OBEYFORM to LIKE The LIKE attribute of the ADD command performs a function similar to the OBEYFORM attribute of the INFO command: • • Use the LIKE attribute to quickly add one or more similar objects to the current configuration file. Use the OBEYFORM attribute to see and change the attributes of new objects before adding them to the configuration file.
Displaying Information About the Storage Subsystem Introduction to the Storage Subsystem Displaying Information About the Storage Subsystem To display information about storage subsystem devices and processes, see: • • The SCF INFO Command on page 14-104 LISTDEV Information for the Storage Subsystem on page 1-5 LISTDEV Information for the Storage Subsystem You can use the SCF LISTDEV command to display configured information about processes that have a device type and that are known to SCF.
Fault Tolerance Introduction to the Storage Subsystem Fault Tolerance An important concept, and a possible source of confusion for users, is the three ways that the word primary can be used when configuring and managing devices. Primary Processor An IOP runs in two processors: primary and backup. The PRIMARYCPU and BACKUPCPU attributes of the ADD command are set when the device is configured. To change which processor runs the primary process, specify that processor number in a PRIMARY command.
2 Storage Subsystem Objects This section describes how storage subsystem components are organized for management through the SCF interface. Topic Page Object Names 2-1 Object Types for the Storage Subsystem 2-3 Object States and Substates 2-2 Object Names Object names are the device or process names you use to specify a particular object in an SCF command. Each object type has its own object-name format. Object Type Object-Name Format Example Object Name ADAPTER $ZZSTO.#type.GRP-g.MOD-m.
Object States and Substates Storage Subsystem Objects The storage subsystem supports these wild-card characters: * Represents a character string of undefined length. For example, to display the object names of all disks managed by the storage subsystem: -> NAMES DISK $* ? Represents a single unknown character in a specific position. For example, to start disks named $DATA00, $DATA01, and so on: -> START DISK $DATA0? You can use wild-card characters in any combination.
Object Types for the Storage Subsystem Storage Subsystem Objects Object Types for the Storage Subsystem Object Type Definition Page The ADAPTER Object A ServerNet adapter, which controls communication between the system and attached devices 2-3 The DISK Object A disk volume, either magnetic or virtual 2-4 The MON Object The Storage Management Foundation (SMF) master process 2-7 The POOL Object A storage pool 2-8 The PROFILE Object A method used to preconfigure disks 2-8 The SCSI Object
Storage Subsystem Objects The DISK Object GRP-g.MOD-m.SLOT-s is the physical location (group, module, and slot) of the adapter. g cannot have a leading zero. Wild-card characters are supported. Examples $ZZSTO.#PMF.GRP-1.MOD-1.SLOT-50 $ZZSTO.#IOMF.GRP-11.MOD-1.SLOT-55 $ZZSTO.#SNDA.SAC-1.GRP-1.MOD-1.
The DISK Object Storage Subsystem Objects Examples $DATA00-P $DATA00-M $DATA00-B $DATA00-MB $DATA03 Object States and Substates of Magnetic Disks The object state and substate of a magnetic disk provide current status information about the disk or a path to that disk. Table 2-1. Object States and Substates of Magnetic Disks (page 1 of 2) State Substate Caused By Description SERVICING -- -- The disk volume or disk path is in transition and is unavailable due to a pending service operation.
The DISK Object Storage Subsystem Objects Table 2-1. Object States and Substates of Magnetic Disks (page 2 of 2) State Substate Caused By Description INACCESSIBLE Processor halts All paths to the processor are down. PREMATURETAKEOVER Improper sequence of commands The backup disk process was asked to take over for the primary disk process before the backup disk process had enough information.
The MON Object Storage Subsystem Objects Virtual Disk Object States Table 2-2. Virtual Disk Object States SCF State Description STARTED Accessible STARTING In transition to the STARTED state STOPPED Inaccessible The MON Object The MON object represents the $ZSMS Storage Management Foundation (SMF) master process, which maintains information about storage pools and virtual disks on the system.
The POOL Object Storage Subsystem Objects The POOL Object The POOL object represents a storage pool, which is a collection of magnetic disk volumes, all on the same system. A POOL object represents a resource of spaces where data files can be placed. Virtual disk processes can create files across volumes of a storage pool. A storage pool can have up to 144 magnetic disk volumes. The number of storage pools on a system is limited only by the current size of the destination control table (DCT).
The PROFILE Object Storage Subsystem Objects The PROFILE object has this format: $ZZSTO.INTERNAL-DISK[-groupnum ] $ZZSTO is the storage subsystem manager. INTERNAL-DISK is the type of disk for which a storage subsystem profile can be configured. -groupnum is the enclosure number to which a user-configured profile applies. groupnum cannot have a leading zero. The default standard profile has no group number and can be used to preconfigure any internal disk inserted in a slot in any enclosure.
Storage Subsystem Objects The SCSI Object The SCSI Object The SCSI object represents an Open SCSI device, which is a storage device that uses the small computer system interface (SCSI) to connect the device to the system. The SCSI object can also represent an Open SCSI Fibre Channel device, which is a Fibre Channel device that uses the SCSI protocol to communicate with the system through the Open SCSI I/O process.
Storage Subsystem Objects The TAPE Object which configures and manages all storage objects in the storage subsystem. For more information, see Section 3, Using the Storage Subsystem Manager. The SUBSYS object has this format: $ZZSTO $ZZSTO is the storage subsystem manager process. Wild-card characters are supported. Example $ZZSTO The TAPE Object The TAPE object represents a specific tape drive, which is a storage device for archiving data.

6 Configuring Magnetic Disks This section describes configuring magnetic disks. Magnetic disks share the object type of DISK with virtual disks. See Section 10, Configuring and Managing Virtual Disks. For information about disk load balancing, see Section 8, Disk Load Balancing. For a list of supported disks, see the NonStop S-Series Planning and Configuration Guide and the NonStop NS-Series Planning Guide.
Configuring Magnetic Disks Types of Magnetic Disks Types of Magnetic Disks You can configure four types of magnetic disks for NonStop servers: Type Description Internal SCSI disks that reside in slots 1 through 18 of NonStop S-series system enclosures. 45xx Disks that reside in slots 0 through 7 of a modular disk subsystem outside of NonStop S-series system enclosures. The disk subsystem connects to the server through a ServerNet/DA Adapter (SNDA).
Considerations for M8xxx Fibre Channel Disks Configuring Magnetic Disks Table 6-1.
Configuring Magnetic Disks • • Considerations for ESS Disks AUTOCONFIGURE is not recommended for M8xxx disks. Confirm that this attribute is OFF before adding M8xxx disks. New M8xxx disks that are being used for the first time must be initialized after they have been added. Considerations for ESS Disks • • • • The primary and mirror logical devices (LDEVs) in the ESS must be in different physical array groups. The primary LUN on the primary and backup paths must be the same.
Configuring Magnetic Disks System Disk Configuration System Disk Configuration When you configure the system disk, these restrictions exist: • • • • • You cannot use SCF to configure the system disk. The system generation program configures the system disk. If the system disk is configured improperly, the system halts during system load, and you must use the system generation program to recover.
Automating Disk Configuration Configuring Magnetic Disks Automating Disk Configuration To automate the configuration of internal magnetic disks when you insert the disk into a slot (or, if the system is down, when the next system load occurs), use the ALTER SUBSYS command to set the AUTOCONFIGURE attribute (page 14-88). Automatic configuration enables the system to automatically configure an internal disk when initially detected after a system load, processor reload, or disk insertion. Note.
Configuring Magnetic Disks Enabling Automatic Disk Configuration The storage subsystem looks for a custom profile (page 6-9) for the enclosure. If no custom profile exists, the storage subsystem uses the default profile (page 5-11) to configure the disk. To make internal disk configuration plug and play, enable these attributes: -> ALTER $ZZSTO, AUTOCONFIG ON, AUTOREVIVE ON, AUTOSTART ON 3.
Configuring Internal Magnetic Disks to Start Automatically Configuring Magnetic Disks Configuring Internal Magnetic Disks to Start Automatically Note. HP does not recommend using AUTOSTART with M8xxx Fibre Channel disks.
Configuring Custom Profiles Configuring Magnetic Disks Configuring Custom Profiles You can automatically configure internal magnetic disks by using a custom or default set of attributes, called a profile. This set of attributes has the object type of PROFILE.
Configuring Magnetic Disks Altering a Profile This sequence of actions changes the default attributes for internal disks in enclosure 3: 1. Capture the existing default profile: -> INFO / OUT LOG / PROFILE $ZZSTO.#INTERNAL-DISK, OBEYFORM == STORAGE - Obeyform Information PROFILE \COMM.$ZZSTO.INTERNAL-DISK ADD PROFILE \COMM.$ZZSTO.
Configuring Magnetic Disks Deleting a Custom Profile Deleting a Custom Profile The DELETE PROFILE Command (page 14-102) removes a custom profile from the system configuration database. Considerations for DELETE PROFILE • • You cannot delete the standard profile $ZZSTO.#INTERNAL-DISK. After you delete a custom profile, autoconfiguration uses the default profile. Examples To delete the custom profile for all disks inserted into group 01: -> DELETE PROFILE $ZZSTO.
Configuring Magnetic Disks Mirrored Disk Placement Mirrored Disk Placement Mirroring Without NonStop S-Series Enclosure Interleaving For proper fault tolerance, always install the two disks of a mirrored volume on different SCSI buses: • • For internal disks in a NonStop S-series system enclosure, if you install the primary disk in an odd-numbered slot, install the mirror disk in an even-numbered slot.
Configuring Mirrored Disks Configuring Magnetic Disks Configuring Mirrored Disks The mirroring examples in this section are based on internal SCSI disks. If you are mirroring model 45xx or M8xxx disks, you also need to specify PRIMARYDEVICEID, BACKUPDEVICEID, MIRRORDEVICEID, and MBACKUPDEVICEID attributes.
Configuring Magnetic Disks Changing a Mirrored Volume Into Two Nonmirrored Disks Changing a Mirrored Volume Into Two Nonmirrored Disks This procedure converts a mirrored, internal volume into two nonmirrored disks without destroying files on either disk. 1.

Restart the disk process: -> START $DATA01 5.
Configuring Magnetic Disks Remirroring Disks Online Remirroring Disks Online You can perform these tasks without stopping the entire disk volume: • • • • Change the disk configuration from an unmirrored configuration to a mirrored configuration Relocate both the mirror disk and primary disk to new slots Unmirror a disk volume Switch the roles of the two disks of a mirror disk volume Throughout the performance of these tasks, a primary disk drive is always available to applications.
Remirroring Disks Online Configuring Magnetic Disks Considerations for ALTER DISK, SWAPMIRROR, and Online Disk Remirroring • • • The SWAPMIRROR attribute causes the two disk drives of a mirrored disk volume to switch roles: ° ° • The mirror disk drive becomes the primary disk drive. To delete the paths to a primary disk drive when you perform online disk remirroring, you must first use an ALTER DISK, SWAPMIRROR command so that the primary disk drive becomes the mirror disk drive.
Configuring Magnetic Disks Remirroring Disks Online Example of Online Disk Remirroring Note. OSM automatically recognizes online remirrored disks. TSM does not. Anytime you use TSM in conjunction with online disk remirroring, observe these rules: • • Before issuing a sequence of SCF commands that implements online disk remirroring, always stop the TSM process. After you have issued the commands and before you exit SCF, make sure to restart the TSM process. For example: 1.
Configuring Magnetic Disks Adding a Magnetic Disk the primary. You must therefore use the SWAPMIRROR attribute so that the primary disk drive becomes the mirror disk drive: -> ALTER DISK $DATA1, SWAPMIRROR This command converts the original mirror disk drive into the primary, thus making it available to applications. 5. After the disk drive originally serving as the primary has become the mirror, you can issue these commands: -> STOP DISK $DATA1-M -> STOP DISK $DATA1-MB -> DELETE DISK $DATA1-M 6.
Adding a Magnetic Disk Configuring Magnetic Disks Adding a Magnetic Disk Use this procedure for internal disks if autoconfiguration is not enabled. 1. For the PRIMARYLOCATION attribute, note the group, module, and slot location where you install the disk. 2. Add the disk: -> ADD DISK $DATA02, SENDTO STORAGE, PRIMARYLOCATION (1,1,3) 3. Verify the attributes recorded in the system configuration database: -> INFO $DATA02, DETAIL 4. See Starting a Magnetic Disk on page 7-3.

Configuring Magnetic Disks Adding a Similar Disk to Another System For 45xx, M8xxx, and ESS disks, PRIMARYLOCATION and MIRRORLOCATION are the storage adapter locations instead of disk locations, so the adapter location attributes do not automatically determine the SAC and DEVICEID attributes. You must make sure that every path for the new disk differs in some way (group, module, slot, SAC number, or device ID) from every other path configured to every device on the system. 3.
Configuring Magnetic Disks Altering Magnetic Disk Attribute Values Altering Magnetic Disk Attribute Values Use the ALTER DISK Command (page 14-51) to change configured attributes for magnetic disks.

Naming a Magnetic Disk Configuring Magnetic Disks Naming a Magnetic Disk All magnetic disk volumes have two names: a default volume name and an alternate volume name. Both can be assigned the same name when you label a volume (by using either the RENAME DISK or ALTER DISK, LABEL command): • • Use the RENAME DISK command when you want to retain use of all the files that reside on the disk you are renaming. Use the ALTER DISK, LABEL command when you want to erase all files on the disk. Caution.
Configuring Magnetic Disks Resolving Disk-Naming Conflicts Resolving Disk-Naming Conflicts When a disk is started, the storage subsystem verifies that the configured name of the disk matches one of the names on the disk label and, if necessary, changes the configured name. Before changing the configured name, the storage subsystem must also verify the new name is not being used by another process. The sequence of events is: 1.
Configuring Magnetic Disks • • Changing the Volume Name and Alternate Volume Name You cannot rename a disk that resides in a storage pool. If you do, the pool process and virtual disks are not informed of the name change. Therefore, before letting you rename a magnetic disk in a storage pool, the storage subsystem manager issues a warning regarding the possible effects on the storage pool process and virtual disks.
Configuring Magnetic Disks Changing Either the Volume Name or Alternate Volume Name Changing Either the Volume Name or Alternate Volume Name The VOLNAME attribute (page 14-67) and ALTNAME attribute (page 14-53) of the ALTER DISK command change the volume name and alternate volume name, respectively, of a stopped disk. When a disk is started, SCF uses the name in the system configuration database to bring up the disk.
Configuring Magnetic Disks Changing Either the Volume Name or Alternate Volume Name 4. View the new volume name: -> INFO $DATA02, LABEL The volume name in the display should be $DEF00. 5. Start the disk: -> START $DATA02 Starting the disk changes the name of the $DATA02 disk to $DEF00 in the system configuration database. 6.
Configuring Magnetic Disks Changing the Volume Name and Alternate Volume Name (Deleting Files) Changing the Volume Name and Alternate Volume Name (Deleting Files) The LABEL attribute (page 14-59) of the ALTER DISK command changes the volume name and deletes all files from the volume. Considerations for LABEL and Magnetic Disks Cautions. • • • The ALTER DISK, LABEL command erases any existing files on the volume that you are labeling.
Configuring Magnetic Disks • Changing the Volume Name and Alternate Volume Name (Deleting Files) When you use the START DISK command on a volume (or when you load the system from tape), SCF uses the default volume name to bring up the disk unless this name is being used by some other device or process. If the default volume name is in use, the storage subsystem automatically uses the alternate volume name.
Configuring Magnetic Disks Relabeling and Initializing a Magnetic Disk Relabeling and Initializing a Magnetic Disk The INITIALIZE DISK Command (page 14-112) re-creates the label and initializes magnetic disk information such as the spare-tracks table. Caution. The INITIALIZE command deletes all existing files on the volume.
Configuring Magnetic Disks Deleting a Magnetic Disk Deleting a Magnetic Disk The DELETE DISK Command (page 14-100) removes a magnetic disk from the system configuration database. Considerations for DELETE DISK and Magnetic Disks • • • • • A disk volume must be STOPPED or not running before you can delete it. You can delete a mirror half of a disk volume while the disk volume is in a STARTED state. You cannot delete only the primary half of a mirrored volume.
7 Managing Magnetic Disks This section describes managing magnetic disks. Magnetic disks share the object type of DISK with virtual disks. See Section 10, Configuring and Managing Virtual Disks). For information about disk load balancing, see Section 8, Disk Load Balancing.
Managing Magnetic Disks Managing Disks Managing Disks When managing disks, review these special considerations: • • • Managing the System Disk on page 7-2 Recovering From the Loss of a Path to a Disk on page 7-2 Troubleshooting Disks on page 7-2 Managing the System Disk You cannot stop access to the system disk because important processes have their object files and swap files on it. Therefore, you cannot stop the last path to the system disk.
Managing Magnetic Disks Starting a Magnetic Disk Starting a Magnetic Disk The START DISK Command (page 14-131) makes a stopped disk accessible to user processes. When finished, the disk is in the STARTED state. Considerations for START DISK • • • • • • New M8xxx disks that have been added and are being used for the first time must be initialized before they can be started. If you are starting a mirrored volume, see Considerations When Reviving a Mirrored Volume on page 7-4.
Managing Magnetic Disks Reviving a Mirrored Disk 4. Confirm that the disk has started: -> STATUS $DISK00 STORAGE - Status DISK \COMM.$DISK00 LDev Primary Backup Mirror 212 *STARTED STARTED *STARTED MirrorBackup STARTED Primary PID 9,262 Backup PID 8,271 5. If the START DISK command fails, see the information on troubleshooting disk drives on the CSSI web at http://h71033.www7.hp.com/ (Technical Documentation>CSSI Web).
Managing Magnetic Disks Starting a Mirrored Disk Starting a Mirrored Disk 1. Verify the current state of the disk volume: -> STATUS $DSMSCM-* STORAGE - Detailed Status DISK \ALM171.$DSMSCM Disk Path Information: LDev Path Status 98 98 98 98 PRIMARY BACKUP MIRROR MIRROR-BACKUP ACTIVE INACTIVE ACTIVE INACTIVE State Substate STOPPED STOPPED STOPPED STOPPED DOWN DOWN DOWN DOWN Primary PID 0,21 0,21 0,21 0,21 Backup PID 1,15 1,15 1,15 1,15 2.
Managing Magnetic Disks Starting a Mirrored Disk To preserve the older disk and copy it to the disk that has the newer time stamp, start a path to the older disk first. This action causes an update to its timestamp, making it more recent. Then you can start the rest of the volume. To monitor the progress of the revive operation, periodically issue this command: -> STATUS $DSMSCM, DETAIL STORAGE - Detailed Status DISK \ALM171.
Managing Magnetic Disks Changing the Speed of a Revive Operation Changing the Speed of a Revive Operation While a revive operation is in progress, you can use the ALTER command to change the speed of a revive operation. Considerations for Changing the Speed of a Revive Operation • • The speed of all future revive operations is also changed. During system installation, the system administrator should tailor the REVIVEPRIORITY and REVIVERATE attributes for your system.
Managing Magnetic Disks Temporarily Stopping a Revive Operation If you have enabled automatic sector reallocation, the system spares the sector and the revive operation resumes. If automatic sector reallocation is disabled, see Temporarily Stopping a Revive Operation on page 7-8. • Nonfatal checksum errors have stalled a revive operation or put it into a loop. Symptoms are: ° ° ° The revive interval in a STATUS, DETAIL display has become large. The Current Logical Sector remains unchanged.
Managing Magnetic Disks Stopping a Magnetic Disk Stopping a Magnetic Disk These two commands stop access to a magnetic disk: • • STOP DISK command—stops access in an orderly manner ABORT DISK command—stops access immediately Stopping a Disk With the STOP DISK Command The STOP DISK Command (page 14-148) stops access to a magnetic disk in an orderly manner. When finished, the disk is in the STOPPED state, substate DOWN. The disk remains configured in the system configuration database.
Managing Magnetic Disks Stopping a Magnetic Disk With the ABORT DISK Command Stopping a Magnetic Disk With the ABORT DISK Command The ABORT DISK Command (page 14-5) stops access to a magnetic disk when the disk or path to the disk either: • • Is malfunctioning but has not been brought down by the disk Must be removed from the system (but the system currently cannot be reconfigured) Considerations for ABORT DISK • • • • • • • Do not used the ABORT DISK, FORCED option on the system disk.
Managing Magnetic Disks Resetting a Magnetic Disk 3. Confirm that the disk is in the STOPPED state, substate HARDDOWN: -> STATUS $AUDIT-* STORAGE - Status DISK \COMM.
Managing Magnetic Disks Considerations for RESET DISK Considerations for RESET DISK • • The RESET command is ignored if the process is started. If the disk is in the STARTING state, substate REVIVE, the disk process is suspended in that state until either another START command restarts the revive operation or a STOP command terminates the revive operation. Resetting One Magnetic Disk 1. Check the current status of the disk: -> STATUS $DISK00-* 2.
Managing Magnetic Disks Resetting a Group of Magnetic Disks Resetting a Group of Magnetic Disks 1. Identify disks that have paths that are not running: -> STATUS DISK $*-*, SEL NOT STARTED, SUB MAGNETIC 2. Prepare all nonrunning disk paths for a subsequent START command: -> RESET DISK $* 3. To prevent a START DISK command with a wild-card disk name from failing if some disk paths do not start: -> ALLOW ALL ERRORS 4. To prevent a specified disk path from starting: -> ABORT DISK $disk{-P |-B |-M | -MB } 5.
Managing Magnetic Disks Sparing a Defective Sector Sparing a Defective Sector Sector sparing is the process of moving the data on a physically defective sector to a different sector and preventing data from using that defective sector again.
Managing Magnetic Disks Controlling Whether $ZRD9 Starts Automatically After a System Load To disable automatic sector reallocation: > STOP $ZRD9 You might want to disable $ZRD9 if you choose to manually spare a sector. Controlling Whether $ZRD9 Starts Automatically After a System Load • To ensure that $ZRD9 does not start automatically after a system load, do one of the following: ° Stop the process and reconfigure it to be started manually: -> ABORT PROCESS $ZZKRN.
Managing Magnetic Disks Sparing a Sector Manually 1. Confirm that the address reported in the error message also appears in an INFO DISK, BAD report: -> INFO $DATA00, BAD 2. Spare the sector containing the address identified in the BAD report. -> CONTROL $DATA00-M, SPARE %H795C The CONTROL command assigns an alternate sector for the data in the spared sector and makes an entry into the defect log.
Managing Magnetic Disks Correcting Doubly Allocated File Extents Correcting Doubly Allocated File Extents The REBUILDDFS attribute (page 14-95) of the CONTROL DISK command rebuilds the disk free space table. This process also gets rid of doubly allocated file extents. File extent overlaps (doubly allocated file extents) are caused by a hardware or software error.
Managing Magnetic Disks Troubleshooting Doubly Allocated File Extents Troubleshooting Doubly Allocated File Extents 1. Repeat Identifying Doubly Allocated File Extents on page 7-17 to see whether any doubly allocated file extents remain: • • If none remain, you are finished with the procedure and you can restart applications. If doubly allocated file extents remain, continue to the next step. 2.
Managing Magnetic Disks Replacing the Bootstrap Program Replacing the Bootstrap Program Note. The REPLACEBOOT attribute does not apply to Integrity NonStop NS-series servers. Instead, the bootstrap program is installed through firmware update into flash memory. The REPLACEBOOT attribute (page 14-95) of the CONTROL DISK command replaces the disk bootstrap program.
Managing Magnetic Disks Replacing the Disk Bootstrap Program on a Mirrored Volume (NonStop S-Series Servers) 4. Replace the bootstrap program on the primary disk: -> CONTROL DISK $SYSTEM, REPLACEBOOT $SYSTEM.SYSnn.SYSDISC 5. To facilitate recovery of a mirrored volume in the event of failure, SCF asks, Do you want to ABORT $SYSTEM-M? Type yes. Caution. If you type no, the REPLACEBOOT operation updates the diskboot file on both disks simultaneously.
Managing Magnetic Disks Replacing the Disk Bootstrap Program on a Nonmirrored Volume (NonStop S-Series Servers) Replacing the Disk Bootstrap Program on a Nonmirrored Volume (NonStop S-Series Servers) This procedure replaces the disk bootstrap program on an unmirrored volume of a NonStop S-series server. The REPLACEBOOT attribute does not apply to Integrity NonStop NS-series servers. Instead, the bootstrap program is installed through firmware update into flash memory. Caution.
Managing Magnetic Disks Enabling and Disabling File Opens on a Magnetic Disk Enabling and Disabling File Opens on a Magnetic Disk Preventing File Opens on a Magnetic Disk The STOPOPENS DISK Command (page 14-153) prevents applications from opening files on a specific magnetic disk. Considerations for STOPOPENS DISK Caution. Do not issue a STOPOPENS DISK command on the system disk. Issuing a STOPOPENS DISK command on the system disk makes it inaccessible to file-open attempts.
Managing Magnetic Disks Allowing File Opens on a Magnetic Disk Allowing File Opens on a Magnetic Disk The ALLOWOPENS DISK Command (page 14-49) lets applications open files on a specific magnetic disk.
Managing Magnetic Disks Swapping Processors for a Disk Swapping Processors for a Disk The PRIMARY DISK Command (page 14-116) swaps the primary and backup processors for a disk. The current primary processor becomes the backup processor, and the backup processor becomes the primary processor, but the PRIMARYCPU and BACKUPCPU values stay the same. Note. To change the primary or backup processor values for a disk, stop all the disk paths (STOP DISK command) or terminate the disk process (RESET DISK, FORCED).

8 Disk Load Balancing Disk load balancing seeks to distribute the disk work load across all fabrics and processors in the system. This subsection describes load balancing between the X and Y fabrics and pairs of processors in a NonStop S-series processor enclosure. A processor enclosure and its I/O enclosures are called a topology branch. The principles that apply to the internal disks in these examples also apply to 45xx disks in a modular disk subsystem.
Disk Load Balancing Between Processors Disk Load Balancing For example, if $OPER on the PMF CRU in slot 50 is balanced between the X and Y fabrics, the primary (-P or -B) disk OR the mirror (-M or -MB) disk has an asterisk in a detailed INFO ADAPTER display: Slot 50: 2 $OPER-MB … 1 $OPER-P STARTED 0,298 1,269 *STARTED 0,298 1,269 Correspondingly, if $OPER on the PMF CRU in slot 55 is balanced between X and Y, the primary (-P or -B) disk OR the mirror (-M or -MB) disk has an asterisk: Slot 55: 2 $OP
Guidelines for All G-Series RVUs Disk Load Balancing Guidelines for All G-Series RVUs Regardless of RVU: • • • When you change a disk path or primary processor, the change does not actually take place until the next I/O action on the disk. The active paths to any mirrored disk should be either the primary and mirror paths or the backup and mirror-backup paths. This distribution ensures fault-tolerance because the disks are accessed through separate system components.
Topology Branch Example for G06.

Disk Load Balancing on G06.10 and Earlier RVUs Disk Load Balancing Disk Load Balancing on G06.10 and Earlier RVUs Understanding SAC Ownership On G06.10 and earlier RVUs each SAC is owned by a processor. A mirrored volume can communicate with its processors through up to four SACs. These events can cause SAC ownership to change: • • • A hardware failure along an active data path to that SAC. A PRIMARY command on a started disk. A processor failure or halt on a primary processor.

PRIMARY Command Function in G05.00 and Earlier Disk Load Balancing $D0203 also changes primary processors in because: 1. The disk process executing in processor 2 attempts to access $D0203-P. The path to $D0203-P on the X fabric leads through SAC 2. Because of the PRIMARY command on the other disk, this SAC is now owned by processor 3. Because the disk process is executing in processor 2, the disk access fails. 2.

Configuring and Managing Storage Pools for Magnetic Disks Adding a Magnetic Disk to a Storage Pool Adding a Magnetic Disk to a Storage Pool The ALTER DISK Command (page 14-51) adds a disk to an SMF storage pool. Considerations for Adding a Magnetic Disk to a Storage Pool • • • • All the magnetic disks in a storage pool must be on the same system. Up to 144 magnetic disk volumes can be placed in a pool. A magnetic disk volume can be in only one storage pool at a given time.
Configuring and Managing Storage Pools for Magnetic Disks • Altering Storage Pool Attribute Values Avoid overriding any safety checks whenever possible. Excluding a disk from a storage pool even though a discrepancy exists could have severe consequences. For example, storage-managed files on a physical volume are still accessible after the physical volume has been excluded from a storage pool, but the catalog for the storage pool is no longer in a consistent state.
Configuring and Managing Storage Pools for Magnetic Disks Deleting a Storage Pool 4. Restart the storage pool: -> START $POOL00 Deleting a Storage Pool Use the DELETE POOL Command on page 14-101 to delete a storage pool. Considerations for DELETE POOL • • • • • • • • Before deleting a storage pool process from the system configuration database, you must delete the virtual disks associated with the pool and reconfigure the physical volumes.

D Upgrade and Replacement Procedures Replacing a Tape Drive If you physically remove a tape drive and replace it with another tape drive that is controlled by the same adapter, the tape process automatically recognizes the new tape drive. For other details about installing or removing a tape drive, see the documentation that comes with the tape drive or contact your service provider. 1. Stop the tape drive: -> STOP $TAPE0 2. Verify the tape drive is in the STOPPED state: -> STATUS $TAPE0 3.
Upgrade and Replacement Procedures Replacing an Open SCSI Device Replacing an Open SCSI Device To replace an Open SCSI device: 1. Stop access to the device: -> STOP $S11500 2. Verify the device is in the STOPPED state: -> STATUS $S11500 3. Physically remove the device from the SCSI chain. 4. Configure the SCSI ID and LUN on the device according to the manufacturer’s instructions. 5. Physically install the new device in the SCSI chain. 6.
