1 About External Storage Unless otherwise specified, the term P9000 in this guide refers to the following disk array: • P9500 Disk Array The GUI illustrations in this guide were created using a Windows computer with the Internet Explorer browser. Actual windows may differ depending on the operating system and browser used. GUI contents also vary with licensed program products, storage system models, and firmware versions.
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 to 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.
Figure 2 Unifying connections from a host to different storage systems 10 About External Storage
2 Interoperability with other products and functions You can use the P9500 program products to utilize and manage the external volumes you have set using External Storage. For the operations and notes on each program product, see the respective user guides. LUN Manager and Configuration File Loader If you set the emulation type for the open system as you map the external volume, you need to set the LU path for the mapped volume using LUN Manager.
Performance Monitor Consider the following for Performance Monitor: • Performance Monitor can be used to display the monitoring information about the external volumes. • Mapped volumes can be used for Auto LUN. For a configuration example of Auto LUN, see “Auto LUN operations ” (page 13). Continuous Access Synchronous and Continuous Access Synchronous Z Mapped volumes can be used for Continuous Access Synchronous and for Continuous Access Synchronous Z.
Examples of using external volumes with other products For the following P9500 program products, the examples of using external volumes are described in the following sections: • “Auto LUN operations ” (page 13) • “Continuous Access Synchronous operations” (page 14) • “Continuous Access Journal operations” (page 15) • “Business Copy operations” (page 16) • “Snapshot operations” (page 17) Auto LUN operations Figure 3 (page 14) shows the use of an external volume for the Auto LUN operation.
Figure 3 Example of the Auto LUN operation Continuous Access Synchronous operations Figure 4 (page 15) shows the use of an external volume for the Continuous Access Synchronous operation. The mapped external volume is set as the S-VOL of the Continuous Access Synchronous pair, and the volume in the local storage system that is connected as the multipoint control unit (MCU) is set as the P-VOL of the Continuous Access Synchronous pair.
Figure 4 Example of the Continuous Access Synchronous operation Continuous Access Journal operations Figure 5 (page 16) shows the use of an external volume for the Continuous Access Journal operation. The mapped external volume is set as the S-VOL of the Continuous Access Journal pair, and the volume in the local storage system that is connected as the MCU is set as the P-VOL of the Continuous Access Journal pair.
Figure 5 Example of the Continuous Access Journal operation Business Copy operations Figure 6 (page 17) shows the use of an external volume for the Business Copy operation. The mapped external volume is set as the S-VOL of the Business Copy pair, and the local storage system internal volume is set as the P-VOL of the Business Copy pair. For details on Business Copy, see the HP P9000 Business Copy User Guide. The procedure for the operation is as follows: 1.
Figure 6 Example of the Business Copy operation Snapshot operations “Example of the Snapshot operation” (page 18) shows the use of an external volume for the Snapshot operation. The mapped external volume is set as a pool-VOL of the Snapshot pair. For details on Snapshot, see the HP P9000 Snapshot User Guide. The procedure for the operation is as follows: 1. Use External Storage to map a volume in the external storage system as an internal volume of the local storage system.

3 Key terms This chapter explains key terms related to External Storage operation.
Remote Web Console computer User-supplied computer that operates Remote Web Console. External Storage A program product that enables the operation of multiple storage systems connected to the P9500 storage system as if they were all in one storage system and provides common management tools and software. External volume It is a volume in the external storage system mapped as a volume of the connected storage system by using External Storage.
Storage systems and external paths Before using 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 ports, which is connected with the cable, is called the "external path". The Fibre Channel port of the local storage system is set to connect to the host by default.
4 Prerequisites This chapter describes the requirements and preparations for External Storage operations. Configuring External Storage Before configuring the External Storage settings, answer the following: • Which ports can be connected to external storage systems? See “Choosing external port” (page 22). • Which external storage system and volumes should be mapped as the internal virtual volumes? See “Choosing and mapping external volumes” (page 22).
You cannot map an external volume whose capacity is smaller than the minimum available capacity. For example, you cannot map an external volume of 10 GB as an internal volume requiring at least 30 GB. The maximum or minimum available capacity of an external volume depends on the emulation type that is set when the volume is mapped.
Residency operation, see the HP P9000 Performance for Open and Mainframe Systems User Guide. NOTE: When you set the cache mode, note the following: • Data that is not written by the host (for example, data written by Business Copy) is asynchronously destaged to the external storage system regardless of the Cache Mode setting.
the ports of the external storage system) will be displayed in a dialog box when you map an external volume. In this dialog box, you can set external paths by selecting the starting points and the ending points of the paths according to the actual cable connections. Setting of redundant external paths You can set redundant external paths (add alternate paths) when you set the external paths. You can also add an alternate path or change the priority after completing the mapping of the external volume.
Figure 11 (page 26) 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. Therefore, the setting of the alternate path is enabled. In Figure 12 (page 26), two paths are also set between the internal volume and the external volume.
Figure 13 When the path mode is Multi mode Examples of switching I/O execution paths to alternate paths (when the path mode is Single mode) Figure 14 (page 28) shows an example of the case 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.
Figure 14 When the path mode is Single mode Examples of switching I/O execution paths to alternate paths (when the path mode is Single mode and there is at least one alternate path in Standby status) Figure 15 (page 29) shows an example of the case when the path mode is Single mode, and there are the alternate paths in the Normal status and the Standby status. Figure 16 (page 29) shows another example of the case when the path mode is Single mode.
Figure 15 Single mode with alternate paths in Normal and Standby Figure 16 Single mode with alternate paths in Standby only Configuring External Storage 29
Connecting mainframe volumes Mainframe volumes, that pre-exist on an external storage system and are accessed by FICON channels, cannot connect directly to the P9500 storage system as an external volume. The P9500 storage system does not recognize these volumes because of the fibre channel.
You can set the mapping policy in advance and choose 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. If you can specify which external port to search for, you can reduce the operation time by executing the port discovery manually.
Supported external storage systems are listed on the HP Single Point of Connectivity Knowledge (SPOCK) website: http://www.hp.com/storage/spock. External Storage requirements The following table describes the External Storage requirements.
• 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 virtual volume, is not accessed from a host that is connected to the external storage system. ◦ Make sure that the external volume, which has been mapped as an internal virtual volume, is not manipulated by a copy function or some other functions of the external storage system.

Figure 18 When the external volume capacity is bigger than the basic capacity of specified emulation type (example of the OPEN-3 emulation type) Figure 19 When the external volume capacity is smaller than the basic capacity of specified emulation type Guidelines for mainframe volumes • If you plan to use the mapped external volume from the mainframe operating system (for example, the volume is mapped with the setting of 3390-x mainframe emulation type), you need to select the external volume that consist
• For the external volume, for which the Cache Mode is set to Disable, the bind mode for the Cache Residency operation is not available. • If you use the mapped external volume for the Cache Residency operation and set the bind mode, the cache of twice as much capacity as the user data is required for the Cache Residency operation. Creating LUSE volume guidelines • LUSE is not supported with mainframe volumes. • Do not combine LDEVs of multiple external volumes to create a LUSE volume.
system, the processing speed of Read and Write operations becomes slow. In this case, the I/Os from the mainframe host may become MIH error. • If the host connected to the local storage system issues too many I/Os to be processed by the external storage system, the commands from the host may possibly be timed out.
For more information about setting the queue of commands, see “Changing the port setting of the external storage system” (page 56). • When using external volumes of AMS2000 series storage system with a copying program product, the copy operation needs to be distributed to two or more RAID groups. There is an upper bound to the number of pairs that can be used for initial copy or resynchronization.
5 Flowchart This chapter describes the flowchart of the External Storage operations. Overview of operations to make external volumes usable from a host The following flowchart illustrates External Storage operations that make external volumes usable from a host. Figure 20 Making external volumes usable from a host The procedure for making the external volumes usable from a host follows: 1. Prepare a volume in the external storage system. 2.
Overview of operations after making external volumes usable from a host After making external volumes usable from a host, External Storage enables you to execute the following operations. Preparing to manipulate the power supply of the storage systems You must follow specific procedures if you want to manipulate the power supply of the storage systems when external volumes are used.
6 Performing External Storage operations This chapter explains how to set the external volume using External Storage. Setting ports Setting ports of external storage systems This section describes the procedure for setting the ports of the external storage system. For detailed information, see the documentation for the external storage system you use. To set the port of the external storage system: 1. 2. 3. 4. Set the topology information according to the configuration of the connection (fabric or loop).
5. Select external volumes from the Discovered External Volumes list and enter the external volume group number and their sequential number in the Initial Parity Group ID box, and then click Add. Select whether to create LDEVs in the external volume in Allow Simultaneous Creation of LDEVs. If you want to take over the data of the external volume when you create LDEVs, select Yes in Use External Storage System Configuration, and then enter an LDEV name in the LDEV Name box.
NOTE: When you detach the channel adaptor where external paths exist, it is necessary to delete all external paths beforehand. When the channel adaptor is detached without deleting external paths, it fails in detaching the channel adaptor. Create new path group and configure external paths To create a new path group and configure external paths, you need to perform the mapping operation. For details of the mapping operation, see “Mapping an external volume” (page 41).
Change configured external path priority To change the external path priority, use the Raise Priority command and the Lower Priority command. The following is an example of procedure to make the external path to the currently used path by raising the priority of the external path: To make the external path to the currently used path by raising the priority of the external path: 1. Click External Storage in the Storage Systems tree. The list of available external storage systems appear in the tree. 2.
Changing an external path To change the external path, cancel the current external path configuration (see “Cancel external path configuration” (page 44)), and configure another external path as a new external path (see “Add external path to existing path group” (page 43)). Replace all external paths with newly added external paths This section explains how to change all the current external paths to newly added external paths with an example.
Take the following steps to delete the external path B and add the external path D. 6. 7. Execute the Disconnect External Paths command on the external path B. Disconnect the cable that the external path B uses, and connect the cable that the external path D uses. 8. Cancel the configuration of the external path B, and add the external path D. 9. Click Apply to apply the settings of the external paths B and D. 10. Make sure the status of the external path D is Normal.
To execute the Disconnect External Storage Systems command, see “Disconnecting external storage system or external volume” (page 50). NOTE: When you want to perform the same processing of the Disconnect External Storage Systems command on an individual volume, you can use the Disconnect External Volumes command. If you want to delete the external volume mapping individually, you first need to execute the Disconnect External Volumes command and then the Delete External Volumes command.
To execute the Disconnect External Storage Systems command, see “Disconnecting external storage system or external volume” (page 50). 4. 5. Perform other operations that are required before turning off the local storage system, if there is some. Turn off the power supply of the external storage system. CAUTION: After you have executed the Disconnect External Storage Systems command, but you need to use the mapped external volume again, execute the Reconnect External Storage Systems command.
To turn on the power supply of the local storage system to restart from the turned off status: 1. 2. Turn on the external storage system that contains the external volume, which is mapped as an internal volume. Turn on the power supply of the local storage system. CAUTION: • When the local storage system is turned off after the Disconnect External Storage Systems command is executed, you cannot access the mapped external volume from the local storage system as you just turn the local storage system on.
4. Start the read or write I/O to the local storage system. All read and write I/Os with fibre channel connections should be started. Disconnecting external storage system or external volume Use the Disconnect External Storage Systems command and the Disconnect External Volumes command to disconnect the external volume.
Note the following when executing the Disconnect External Storage Systems command and the Disconnect External Volumes command. • After executing the Disconnect External Storage Systems command or the Disconnect External Volumes command, click Refresh View on the Remote Web Console main window to update the information, and check the current progress status.
8. Click Apply in the Confirm window. The settings are applied to the local storage system and the displayed information for the external volume status in the window becomes Cache Destage. When all the data in the cache memory is written to the external volume, the displayed information for the external volume status in the window becomes Disconnect. When an error occurs, an error message appears. Verify the details in the Confirm window.
3. 4. 5. 6. Select the external storage system. On the menu bar, click Actions, External Storage, and then Reconnect External Storage Systems. The Reconnect External Storage Systems window opens. Confirm the settings and enter the task name in the Task Name box. Click Apply in the Confirm window. The displayed information for the external volume status in the window changes to Checking.
4. 5. 6. 7. 8. On the menu bar, click Actions, External Storage, and then Disconnect External Paths. The Disconnect External Paths window opens. Select one of the following from Disconnect external paths. • By Ports: Displays the ports in the local storage system. Select By Ports to stop the use of all the external paths connected to the specified port in the local storage system. • By External WWNs: Displays the WWNs in the external storage system.
Cache mode and pool volumes When a volume is registered to a pool as a pool volume, the cache mode setting should be the same among all the pool volumes in the pool. Cache mode and remote command devices When the volume is a remote command device, you cannot change the cache mode from Disable to Enable. To change the cache mode of the external volume: 1. Click External Storage in the Storage Systems tree. The list of available external storage systems appear in the tree. 2.
Changing the port setting of the external storage system You can change the setting of the port of the external storage system in the Edit External WWNs window. CAUTION: • If the default setting has no problem, use the default setting as it is. • For the volume used in usual I/O, set I/O Timeout within 15 seconds. • For changing the setting, match the value to the recommended value of the external storage system. To change the port setting of the external storage system: 1.
Command device If the execution of any application that is using the command device is in progress, stop the application. Destage cache memory data All the data in the cache memory must be written into the mapped external volume using the Disconnect External Storage Systems command or the Disconnect External Volumes command. LUSE volumes When it is set as a volume that configures a LUSE volume, you cannot delete the external volume mapping.
NOTE: When you click Yes, the Delete External Volumes operation is performed, however, the data in the cache memory that is not written to the volume is not guaranteed. 8. Click Finish to display the Confirm window. 9. Confirm the settings and enter the task name in the Task Name box. 10. Click Apply in the Confirm window. NOTE: The operation cannot be performed if some parts of the local storage system are blocked.
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 Virtual LVI function. For zero-formatted external volumes, when you select that volume to map, you can use the Virtual LVI function to perform the Write to Control Blocks operation to restore the volume.
NOTE: • Make sure that you do not access the external volume, which has been mapped as a internal volume, from the host that is connected to the external storage system. Also make sure that you do not access the mapped external volume using the function (for example, copy function) of the external storage system. Once you have mapped an external volume as an internal volume, you can access the mapped external volume only from the local storage system side.

B Required external 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. This appendix describes required external volume capacity corresponding to the specified emulation type. Determining required external volume capacity The capacity required for the external volume to be mapped is the total capacity of LDEVs created in the external volume.
Figure 25 LDEV capacity Figure 26 Determining the capacity required for the external volume (OPEN-3) When the capacity of the external volume is 1,610,612,640 (Blocks) and this external volume is mapped with OPEN-3 emulation type, 334 LDEVs, each of which has the base LDEV capacity, can be created at the maximum because the base LDEV capacity of OPEN-3 is 4,818,240 (Blocks). When 334 LDEVs are created, 1,320,480 (Blocks) of the mapped external volume becomes the free space.
For the emulation type for the open system other than OPEN-V, the LDEV capacity that can be made when an external volume is mapped is divisible by 1,440 blocks. For the emulation type for the mainframe system, the LDEV capacity that can be made when an external volume is mapped is an integer when converted into a cylinder.
C Adjusting volume capacities for pairs This appendix provides information for adjusting volume capacities for pairs. Adjusting volume capacities 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 27 (page 87).
