1 Overview of HP StorageWorks XP External Storage Software This chapter provides an overview of XP External Storage.
Figure 1 Unifying Copy Operations between Different Storage Systems Unifying Connections from a Host to Different Storage Systems When a system has multiple storage systems, a host usually needs to connect all storage systems. When a system administrator configures the connections from a host to volumes, they need to follow the different instructions depending on the storage systems.

2 About XP External Storage Operations This chapter explains the functions and the applications of XP External Storage.
Figure 3 Concept of XP External Storage By mapping an external volume as an internal volume using XP External Storage as shown in Figure 3 (page 13), it becomes possible to operate the external volume using Remote Web Console as if it is a volume in the local storage system.
Figure 4 XP External Storage Components This section describes the details on the storage systems, cross-subsystem paths, volumes and mapping paths as shown in Figure 4 (page 14). Storage Systems and Cross-subsystem Paths Before using XP External Storage, connect the Fibre Channel port of the local storage system to the external storage system port with the fiber cable. The route between the ports that are connected with the cable, is called the cross-subsystem path.
local storage system. After the mapping, you can manipulate the external volume from the local storage system in the same way as manipulating an internal volume. When external volumes in external storage systems are mapped as internal volumes in your storage systems, the external volumes can be accessed and copied by hosts connecting to your storage systems, but not by hosts connecting to the external storage systems.
• Using spreadsheets to map external volumes XP External Storage supports Configuration File Loader spreadsheets. These spreadsheets allow you to configure the mapping of multiple external volumes at the same time, which is efficient when mapping large numbers of volumes. For details, see “Using Spreadsheets for XP External Storage Operations” (page 101).
(internal volumes). Identify the volumes in each external storage system that should be mapped as internal volumes. • You cannot access the data that is stored in an external volume beyond the maximum available capacity. For example, if an external volume of 100 GB was mapped as an internal volume of 70 GB, then 30 GB of the external volume would not be accessible from the local storage system side. • You cannot map an external volume whose capacity is smaller than the minimum available capacity.
set to Disable. All I/O to and from the local storage system (either Enable or Disable) always uses cache mode. Write operations are always backed up in duplex cache. ◦ If you select Enable, after receiving the data into the local storage system cache memory , the local storage system signals the host that an I/O operation has completed and then asynchronously destages the data to the external storage system.
If two or more external volumes use the same redundant cross-subsystem paths, these external volumes can be a group. This group is called a path group. In the redundant cross-subsystem paths, the cross-subsystem path that has the highest priority is called the primary path. The cross-subsystem paths other than the primary path are called alternate paths. • Setting of the path groups A path group is automatically set when you map the external volume or when you change a path group by using spreadsheets.
the local storage system for the alternate path. Therefore, CL1 port and CL2 port are specified as shown in the figure. Figure 5 Example of Alternate Path Setting Figure 6 (page 20) illustrates an example of setting an alternate path when a switch is used. Two ports are specified in the local storage system, and connected to the ports in the external storage system through the switch. In this case, two ports of different clusters are specified in the local storage system.
Figure 7 Example of Unavailable Alternate Path Setting Examples of Switching I/O Execution Paths to Alternate Paths This section describes examples of the performance when the I/O execution path is switched to the alternate path for each path mode as follows: • When the path mode is Multi mode • When the path mode is Single mode • When the path mode is Single mode and there is at least one alternate path in the Standby status For the description about the path status, see “Mapping Path Information Di
Figure 8 When the Path Mode is Multi Mode • When the path mode is Single mode Figure 9 (page 23) shows an example of when the path mode is Single mode. When an error occurs in the path that is being used for I/Os, the I/O execution path is switched to the path with the second highest priority. As you restore the path with the priority higher than the currently used path, the I/O execution path is automatically switched to the restored path that has the highest priority.
Figure 9 When the Path Mode is Single Mode • When the path mode is Single mode and there is at least one alternate path in the Standby status Figure 10 (page 24) shows an example of when the path mode is Single mode, and there are alternate paths in Normal status and Standby status. Figure 11 (page 25) shows another example of when the path mode is Single mode. For Figure 11 (page 25), there are alternate paths in Standby status only.
Figure 10 Single Mode with Alternate Paths in Normal and Standby 24 About XP External Storage Operations
Figure 11 Single Mode with Alternate Paths in Standby Only Connecting Mainframe Volumes Mainframe volumes that pre-exist on an external storage system and are accessed by ESCON or FICON channels cannot connect directly to the storage system as an external volume. The storage system does not recognize these volumes because of Fibre Channel.
For the volume formatting and Write to Control Blocks operation procedures, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User Guide. Connecting Open Systems Volumes Open systems volumes in external storage system connect to and are recognized by the storage system as open systems volumes, without requiring reformatting. Reformatting is not required because the connection between the storage system and the external storage system is Fibre Channel.
the external storage system can be displayed in a dialog box of XP External Storage when you execute port discovery. You can set in advance the mapping policy on whether to execute port discovery automatically or manually. If port discovery is executed automatically, WWNs connected to all the external ports of the local storage system will be searched for. If port discovery is executed manually, you can select a specific external port and limit the scope to search WWNs.
see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User Guide. Go to step 4. 3. If you set the emulation type for the mainframe system when you map the volume, the status of the mapped volume becomes Blockade. Format the volume using the VLL function. For zero-formatted external volumes, when you select that volume to map, you can use the VLL function to perform the Write to Control Blocks operation to restore the volume.
From the host, you can access the external storage system volumes that have not been mapped as internal volumes. There is no restriction. Figure 13 (page 29) illustrates using existing data in a mapped external volume. Figure 13 Using the Existing Data in the Mapped External Volume Interoperability with other Products and Functions You can use XP disk array program products to use and manage the external volumes you have set using XP External Storage.
Virtual LVI/LUN (VLL) Consider the following for Virtual LVI/LUN (VLL): • If you set the emulation type for the mainframe system as you map the external volume, you need to format the mapped volume or perform the Write to Control Blocks operation using the VLL function before you use the external volume. For the volume formatting operation and Write to Control Blocks operation procedures, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User Guide.
HP StorageWorks XP Snapshot Software Mapped volumes can be used for XP Snapshot. Consider the following for XP Snapshot: • Both internal and external volumes cannot be mixed in one pool. • All external volumes in the same pool must be in the same Cache Mode. HP StorageWorks XP Thin Provisioning Software Mapped volumes can be used for XP Thin Provisioning. Consider the following for XP Thin Provisioning: • Both internal and external volumes cannot be mixed in one pool.
To copy the existing data in the mapped external volume using the copy program products of Remote Web Console such as XP Continuous Access and XP Business Copy, the emulation type of the mapped external volume also has to be OPEN-V. 2. Prepare the local internal volume that has the same capacity as the mapped external volume. Adjust the capacity of the internal volume as it is required using the VLL function.
is not executed automatically. If you need to format the mapped volume, format the volume using the VLL function. For the volume formatting operation procedure, see the HP StorageWorks XP24000/XP20000 Virtual LVI/LUN (VLL) and Volume Shredder User Guide. Go to step 4. 3. If you set the emulation type for the mainframe system when you map the volume, the status of the mapped volume becomes Blockade. Format the volume using the VLL function.
1. Use XP External Storage to map the volume in the external storage system as an internal volume of the local storage system, which is used as RCU for the XP Continuous Access Journal operation. You can select the emulation type of the mapped volume as you required. If you select the emulation type for the open system (such as OPEN-V), go to step 2. If you select the emulation type for the mainframe system (such as 3390-3), go to step 3.
XP Business Copy Operations Figure 17 (page 35) shows the use of an external volume for the XP Business Copy operation. The mapped external volume is set as the S-VOL of the XP Business Copy pair, and the local storage system internal volume is set as the P-VOL of the XP Business Copy pair. For details on XP Business Copy, see the HP StorageWorks XP24000/XP20000 Business Copy Software User Guide. The procedure for the operation is as follows: 1.
XP Snapshot Operations Figure 18 (page 36) shows the use of an external volume for the XP Snapshot operation. The mapped external volume is set as a pool-VOL of the XP Snapshot pair. For details on XP Snapshot, see the HP StorageWorks XP24000/XP20000 Snapshot User Guide. The procedure for the operation is as follows: 1. Use XP External Storage to map a volume in the external storage system as an internal volume of the local storage system.
3 Preparing for XP External Storage Operations This chapter describes the requirements and preparations for XP External Storage operations.
Table 1 XP External Storage Requirements Item Requirement Maximum number of ports in the connected external storage system (WWN is used as a port identification number 1,024 per port Maximum number of external volumes that can be connected 63,232 volumes can be connected. 4,096 volumes can be connected per port.
• Make sure that an external volume is accessed only from the local storage system side once the external volume is mapped. ◦ Make sure that the external volume, which has been mapped as an internal volume, is not accessed from the host that is connected to the external storage system. ◦ Make sure that the external volume, which has been mapped as an internal volume, is not manipulated by the copy function or other function of the external storage system.
Table 3 When the Emulation Type of the External Volume is for Mainframe Application HDD Type FC/SSD SATA Not Recommended Not Recommended Not Recommended Not Recommended Operation from TPF Not Supported Not Supported File Operation from Host Yes Not Recommended Yes Yes Backup Yes Recommended Archive Yes Recommended Database Online Transaction Processing (OLTP) System Volumes (Journal, Check points) (Both of Read and Write) File Operation from Host (Mainly Read) Capacity Guidelines • W
smaller than the actual external volume capacity. The available capacity decreases as much capacity as the data management information area. Figure 20 (page 41) shows an example of when the original capacity of the external volume is bigger than the basic capacity of the emulation type. The emulation type is OPEN-3. Figure 21 (page 41) shows an example of when the original capacity of the external volume is smaller than the basic capacity of the emulation type.
• The attributes that are set for the external volume originally on the external storage system side (such as the port security, the LUN security, the Volume Retention Manager attributes, and so on) are not kept, when the external volume is mapped as an internal volume. If the original attributes are required to be set, set the attributes on the mapped external volume from the local storage system side.
Maintenance Guidelines for an External Storage System • Before you change settings of the external storage system, you must delete the external volume mapping. After you change settings of the external storage system, you must remap the external volume. If you do not remap the volume, the external volume cannot be used in the local storage system.
To keep the load proper, HP recommends the following: ◦ Define volumes of each AMS 2000 series storage system to set the external path number to two. In that case, set the paths to the ports of each controller of the AMS 2000 series storage system. ◦ Set the queue of commands that are issued at the same time from one AMS 2000 series storage system to 500 or less.

B Required Volume Capacity for Each Emulation Type When you map an external volume as an internal volume, you need to specify the emulation type for the mapped volume. The maximum capacity of an external volume depends on the specified emulation type. Determining Required External Volume Capacity The capacity required for the LDEV to be mapped is the total capacity of the data area for storing the actual user data and the control information area for storing the control information.
Figure 45 Idea of LDEV Capacity Figure 46 Example of How to Figure Out the Volume Capacity (For OPEN-3) Capacity List for Each Emulation Type This section explains the LDEV capacity and volume capacity for each emulation type in the units of blocks and cylinders. The numbers of cylinders are calculated from the following formulas.
mainframe system, the LDEV capacity that can be made when an external volume is mapped is an integer when converted into a cylinder.
Table 62 Volume Capacity Information for Each Emulation Type Emulation Type Base LDEV Capacity Blocks Cylinders Minimum LDEV Capacity Blocks Cylinders Maximum Capacity of External Volume Blocks Cylinders Maximum Number of LDEVs1 3380-3 4,818,240 3,346 82,080 57 1,610,612,640 1,118,481 334 3380-3A 4,818,240 3,346 82,080 57 1,610,612,640 1,118,481 334 3380-3B 4,818,240 3,346 82,080 57 1,610,612,640 1,118,481 334 3380-3C 4,818,240 3,346 82,080 57 1,610,612,640 1,118,481 3
C Adjusting the Volume Capacities for Pairs When you create a pair, the capacity of an S-VOL must be the same as that of a P-VOL. To set a desired volume to a pair, you may need to adjust the capacity of the volume. This section describes the procedure for adjusting the volume capacity. For A, B, and C in the following description, see Figure 47 (page 156).
1. 2. 3. Map the external volume (A) as an internal volume (B) of the local storage system. Set the emulation type as same as that of the copy source volume (C). Check the capacity of the internal volume (B) where the external volume (A) is mapped. If the capacity of the mapped external volume (B) is not same as the copy source volume (C), use the VLL function to create a CV that has the same capacity as the copy source volume (C) out of the volume (B). Create a pair.
D The ExPath Tool This appendix explains how to use the ExPath tool. Overview of the ExPath Tool The ExPath tool enables you to perform the Disconnect Volume command and the Check Path & Restore Volume command on the command line. When you use the ExPath tool, you can perform these commands on multiple volumes at a time. If you use the ExPath tool, you can automate a series of operations for backing up or updating data by using a function of the external storage system.
running Remote Web Console, see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide. • The ExPath tool program The ExPath tool is contained in CD-ROM Disc 2, which is named Host PP. Use the ExPath tool version that is synchronized with the storage system microcode version. If the storage system microcode is upgraded, upgrade the ExPath tool on your computer by using the disk that comes with the storage system microcode.
Creating an Authentication File An authentication file is an encrypted file containing a user ID and a password. If the SVP has an IPv6 address, an authentication file is required. To create an authentication file, perform the following command at the command prompt. Syntax -classpath java ”classpath” sanproject.uvmdat.MakeAuthentication svpip UserID Password>An_Authentication_File Parameters Parameter Description classpath Specifies the paths to the JAR files ("./lib/JSanExPthTool.jar;.
; Disconnect svpip 127.0.0.1 login root password disconnect E1-1 E1-2 disconnect E2-1 E2-2 The svpip and login commands are used for writing the authentication information. If no authentication file is created, the authentication information must be written in a command file as shown above. Running the ExPath Tool To run the ExPath tool, write the following command in a batch file, and execute the batch file on the command line. The ExPath tool cannot be started multiple times concurrently.
-1: An error occurred. If multiple external volumes are specified, 0 returns only when all the commands on all the external volumes are finished successfully. When the checkstatus command is executed, different termination codes will return. An error (the termination code -1) occurs under the following conditions: • When a command file contains information about an external volume that does not exist. When the disconnect or checkpath command is executed, the RMI server error (605, 5828) occurs.
login Command Syntax login user-ID password Description Specifies the login user ID and the password. The svpip command must be written before this command. If you specify an authentication file when you run the ExPath tool, this command will be ignored. Parameters Parameter Description user-ID Specifies the user ID of Remote Web Console. password Specifies the password for the user ID of Remote Web Console.
checkpath Command Syntax checkpath ExG-VPG[ ExG-VPG...] Description Resume using external volumes. This command executes the same operation as the Check Paths & Restore Volume command which you perform by using the Volume Operation window. After the checkpath command is performed, the local storage system can access the external volumes. For detailed notes on the checkpath command, see (page 93). The sample file checkPath.txt is provided for your use.
