General instructions 1 Insert the proper connector into the Host Interface Card in the back of the array. (Refer to Connecting a Fibre Channel Array on page 11 for Fibre Channel and Connecting a SCSI Array on page 13 for SCSI). 2 Connect the cable (Fibre Channel or SCSI) from your host system to the Host Interface Card connector on the back of the array. The cable you use depends upon your application, the environment and distance.
3.2.1 Connecting a Fibre Channel Array The Diamond Storage Array supports up to two Fibre Channel Host Interface Cards (HIC). Physical connections and CLI commands contribute to the Fibre Channel topology. 2 Gb HIC uses 2 SFPs to connect up to 2 FC cables The cable you use depends upon your application, the environment and the distance required for your storage area network. To comply with FCC and CE EMI for the 2-gigabit Host Interface Card, use fiber optic cables. Exhibit 3.
Exhibit 3.2-3 Possible 2 gigabit Fibre Channel physical connections depending on which Fibre Channel connection mode has been selected.
3.2.2 Connecting a SCSI Array The SCSI Diamond Storage Array uses a VHDCI connector and SCSI cables to connect to a host. It will automatically detect the type of Host Interface Card it is using without any intervention. connect a cable between the second connector and the next device on the SCSI bus. To connect a SCSI array 1 Insert a SCSI VHDCI connector into the Host 4 Interface Card in the back of the array.
14 SCSI connections
4.0 Determining Drive and Sled Designations The Diamond Storage Array has been designed with 12 sleds, each holding two drives. The easiest way to configure a array is to use all the drives on all the sleds. The firmware uses a numbering system to determine which drives and sleds it is affecting. We recommend that all sled slots are filled contiguously, starting with the first slot next to the management card.
Examples JBOD mode uses 24 LUNs. Each LUN is equivalent to one physical drive. The array will operate with several sleds missing, but the empty sled(s) will be treated as offline and will not be configurable. With a fully populated array, RAID 0 may be configured as 1, 2, 3, 4, 6, or 12 LUNs. As QuickRAID0 1, all 24 physical drives are configured as a single stripe group or LUN.
5.0 Accessing the Array Communicate with the Diamond Storage Array through the Fibre Channel link, the RS-232 port or the Ethernet port using Command Line Interface commands. You may configure and tune the Diamond Storage Array for different environments and applications, update the firmware, monitor internal power and temperature status, report on hardware diagnostics and log failures.
system through a common interface. You use CLI commands or the SNMP page of the ExpressNAV interface to configure up to six unique Trap addresses. A trap is a way for the array to tell the SNMP server that something has happened. SNMP SNMP, or Simple Network Management Protocol, is an application layer protocol that allows network devices to exchange management Exhibit 5.0-1 information.
5.1 In-band CLI Over the Fibre Channel In-band Command Line Interface (CLI) configures and manages the Diamond Storage Array using SCSI-based CLI commands over a Fibre Channel port connection. In-band CLI allows a programmer to configure the Diamond Storage Array while it is moving data. Using a programmer’s interface, CLI commands as described previously in this manual may be implemented. In-band CLI is implemented as part of LUN 0.
A CHECK_CONDITION, INVALID_PARAMETER_IN_CDB will be returned to an initiator that specifies an incorrect Buffer ID, Mode, Length or Buffer Offset. The Mode is always Data (0x2), the Buffer ID is always 0 and the Buffer Offset is always 0. Exhibit 5.1-1 The SCSI command process: reserve the Diamond Storage Array, send the command, release the Diamond Storage Array.
5.2 Serial Port Access The Diamond Storage Array provides remote service operations over the RS-232 serial port using standard terminal emulation software available with most systems.

6.0 Configuring Drives The Diamond Storage Array can be configured as a JBOD, RAID Level 0, RAID Level 1, RAID Level 10 or RAID Level 5 array. Its default is JBOD. RAID is a storage configuration which uses multiple disk drives to increase capacity, performance and/or reliability. You may configure your Diamond Storage Array in several different ways depending on your needs although the Diamond makes some choices for your. The following elements must be considered when you are configuring your Diamond.
RAID Level 10 is used in applications requiring high performance and redundancy, combining the attributes of RAID Levels 1 and 0. The QuickRAID10 command, accessed through the Command Line Interface, allows a simple, out-of-the-box setup of RAID Level 10 groups. The array will operate in degraded mode if a drive fails unless you have enabled Hot Spare sleds. RAID Level 5 RAID Level 5 increases reliability while using fewer disks than mirroring by employing parity redundancy.
6.1 JBOD The Diamond Storage Array is set up in a JBOD (Just a Bunch of Disks) configuration as default. JBOD configuration allows for many individual disk drives to be available for normal storage operations. CAUTION Selecting JBOD configuration causes all previous drive data on the Diamond Storage Array to be erased. Make sure all of your information is backed up before setting up the Diamond Storage Array in a JBOD configuration.
52 JBOD
6.2 RAID Level 0 The Diamond Storage Array can be set up into RAID Level 0 (striping) groups to allow it to read and store data at a higher transfer rate. QuickRAID0, a CLI command, allows you to set up the system as if it were a single drive instead of separate drives. CAUTION Setting RAID configuration causes all previous drive data on the Diamond Storage Array to be erased. Make sure all information is backed up before setting up RAID groups.
7 Reboot the host computer. 8 If sled(s) or drive(s) are physically missing from the array, the entire stripe group (LUN) containing the drive(s) will be unavailable. To determine which drives would be unavailable in various configurations, see Exhibit 6.2-1 and Exhibit 6.2-2. (refer to Accessing the Array on page 17). You should now be in CLI. Continue with the CLI or access the RAID page of the ExpressNAV interface (refer to ATTO ExpressNAV: Browser-based Interface on page 25).

Connect to Diamond Storage Array services (refer to Accessing the Array on page 17) and use Exhibit 6.
6.4 RAID Level 5 RAID Level 5 increases reliability while using fewer disks than mirroring by employing parity redundancy. Distributed parity on multiple drives provides the redundancy to rebuild a failed drive from the remaining good drives. CAUTION 2 Selecting RAID configuration causes all previous drive data on the Diamond Storage Array to be erased. Make sure all information is backed up before configuring RAID groups.

Type set QuickRAID5 2 2 3 Type SaveConfiguration Restart The array is configured into two RAID Level 5 groups with two Hot Spare sleds. Refer to Exhibit 6.
Configuring a partially-populated array The simplest way to attain RAID Level 5 in a partially-populated array (an array with three or more sleds but less than 12 sleds) is to create one RAID Level 5 group, with or without hot spare sleds, encompassing all the available sleds by using the CLI command QuickRAID5 ALL. To set up a partially populated arrays, you must have at least three sleds filling contiguous slots as shown in Exhibit 6.4-4, beginning with the slot closest to the management card.

Connect to Diamond Storage Array services via the RS-232 port or the optional Ethernet management services card (refer to Accessing the Array on page 17).
6.5 RAID Level 10 The Diamond Storage Array can be set up into RAID Level 10 (striped and mirrored) groups to provide greater reliability by simultaneously writing data to two sleds. Each sled partnered through QuickRAID10, a CLI command, has the same data as its partner. CAUTION Note Because the ExpressNAV pages take you through this process easily, the following instructions are based on the CLI commands. Use these instructions as a guide in ExpressNAV.

Reboot the host computer. Type DriveInfo when in CLI or access the Storage Management page of the ExpressNAV interface to determine the setup of the array.
6.6 Rebuilding RAID Configurations If a sled must be removed and a new sled inserted into the Diamond Storage Array while it is configured in a RAID Level 1, 5 or 10, you must rebuild the RAID Level using CLI commands or the ExpressNAV interface. CAUTION Note Drive rebuilding reduces performance. You may want to leave AutoRebuild at the default disabled and manually rebuild during off-peak hours, or use the RebuildPriority command described below.
You must use a SaveConfiguration Restart command to implement the rebuild priority command. To synchronize mirrored drives manually 1 2 Connect to Diamond Storage Array services via the RS-232 port or the optional Ethernet management services card (refer to Accessing the Array on page 17). You should now be in CLI. Continue with the CLI or access the RAID page of the ExpressNAV interface (refer to ATTO ExpressNAV: Browser-based Interface on page 25).
6.7 RAID Interleave Parameters The interleave size sets the amount of data to be written to each drive in a RAID Level group. This is a tunable parameter which takes a single stream of data and breaks it up to use multiple disks per I/O interval. CAUTION 2 Changing this parameter causes all previous drive data on the Diamond Storage Array to be erased. Make sure you back up all information before setting up different interleave sizes.

7.0 Hardware Maintenance The disk drive sleds, blower assemblies, power supplies, host interface cards, and system management card may be replaced with identical or upgraded parts. WARNING The only way to completely de-energize the unit is to turn off both power supplies and unplug both Power Switch Positions power cords from the back of the unit. Turning the power switch to the Stand-by position on one power supply does not completely turn off power to the array; it is not an AC on-off switch.
Exhibit 7-3: The Fibre Channel or SCSI Host Interface Card may be replaced by shutting power down, removing any cable attached to the port, removing the SFP according to manufacturer's instructions, loosening the screws at the top and bottom of the card, then carefully pulling out the unit. Exhibit 7-2: Above, disk drive sled partially pulled out of the Diamond Storage Array. Bottom left, top of disk drive sled.
7.1 Hot Swap Operating Instructions To maintain array up time, individual disk drive sled assemblies, power supplies and blower assemblies can be replaced with the unit fully operational. Special instructions need to be followed to perform these operations. Disk drives 3 The following cautions must be observed when hot swapping disk drives. • Individual disk drive sled assemblies may be replaced while the array is operating with no other intervention only if there is absolutely no activity on that drive.
ClearDiskReservedArea (SledNum, 1) ClearDiskReservedArea (SledNum, 2) Set AtaDiskState (SledNum, 1, ONLINE) Set AtaDiskState (SledNum, 2, ONLINE) 12 The new disk drive sled will be available for system use 10 to 15 seconds after the disk drives spin up and communication is reestablished. 10 Verify correct operation by observing that the green light on the rear of the power supply is lit and that the appropriate power supply light on the system management card on the front of the unit is lit.
7.2 Optional Hot Spare Sled To maintain array up time with minimal risk of data loss, individual sleds which fail may be replaced with a spare sled in some configurations. In most configurations, if a member of a virtual device becomes degraded, you must swap out the faulted sled as defined in Hot Swap Operating Instructions on page 71. If you have not enabled AutoRebuild, you must also start a manual rebuild.
To set up one RAID Level 5 group with one Hot Spare sled To set up two RAID Level 5 groups with Hot Spare sleds 1 Connect to Diamond Storage Array services (refer to Accessing the Array on page 17) and use the CLI or enter ATTO ExpressNAV interface Advanced CLI Configuration page. 1 Connect to Diamond Storage Array services and use the CLI or enter ATTO ExpressNAV interface Advanced CLI Configuration page.
8.0 Copying Drives Copying drives using the DriveCopy CLI command may be necessary on drives in the JBOD configuration. DriveCopy can create a backup of a drive onto another drive sled. If one drive fails, DriveCopy may be used to copy the data off the remaining drive on the sled to another drive on another sled. Once completed, the sled containing the failed drive may be replaced.
76 Copy drives
9.0 Updating Firmware Engineers, technicians and/or system administrators/integrators may update the firmware of the Diamond Storage Array using the Command Line Interface (CLI) or the Advanced CLI Configuration page of the ExpressNAV interface (Refer to ATTO ExpressNAV: Browser-based Interface on page 25) via the RS-232 serial port or the optional Ethernet management services card.

The IP address must be a valid address for your network.
10.0 System Monitoring and Reporting The Diamond Storage Array provides a number of visual, audible and computer system-generated indicators to identify the operational status of the array. System status and error information is readily available to the end user. RS-232 monitoring port and CLI One tool to support a Diamond Storage Array is a host computer with an RS-232 port and terminal emulation software.
The Diamond Storage Array will function under normal external operating temperatures of 5°C and 40°C. Temperature sensors provide data to the software to trip a temperature warning alarm and will, at excessively high or low temperatures, disable disk drive activity to protect the drives. The Diamond reports the temperature via SES, CLI and the ExpressNAV interface as well as the state of the temperature warning alarm (Not Present, OK, Warning, Critical).

10.1 Troubleshooting The Diamond Storage Array provides a number of visual, audible and computer system-generated indicators to identify the operational status of the array. System status and error information is readily available. If your situation is not defined here or elsewhere in the manual, if these solutions do not help, or if you have any questions or concerns about any aspect of operating the array, please contact technical support.
alarm will turn off when the fault condition is cleared or the alarm can be disabled by issuing a PowerAudibleAlarm or AudibleAlarm command via CLI as described in Diagnostic Commands on page 41. Disabling the alarm for a specific error will not silence the alarm for other error conditions.
• If you perform a hardware restart, the Ethernet connection is dropped. You must re-establish the Ethernet connection. • If you enter a command that requires a Save Configuration command in either the serial interface window or the Ethernet connection window, you will not be able to access the inactive window until the Save Configuration command is complete in the active window. • If you still fail to communicate with the array, swap out the management card and try to connect using default settings.
10.2 Resetting Defaults Resetting the Diamond Storage Array to defaults will not alter the RAID configuration, IP configuration or Telnet information. However, resetting the Diamond Storage Array to factory defaults is a last-ditch effort to recover from corrupt configurations or complete failure. All data will be lost.
