For instructions, see the HP StorageWorks Command View XP user guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000/SVS200. Preparing for External Storage XP settings Before using External Storage XP, collect the information necessary for defining its settings. The following information is required: •...
Page 25: External Lu Groups
External LU groups When mapping an external LU as an internal LDEV, you must register the external LU in an external LU group. You can classify external LUs set by External Storage XP into groups according to their use. The group is called an external LU group (ExG).
Page 26: Alternate Paths
If you use an external LU and set Cache Mode to Disable for Cache LUN XP operations, you cannot use the Cache LUN XP Bind mode. For more information, see the HP StorageWorks Cache LUN XP user guide for XP12000/XP10000/SVS200.
Page 27: Example Of An Alternate Path Configuration
If you have not configured any alternate paths, host I/O operations are suspended when the primary path becomes unavailable (such as during array maintenance operations or following a failure in the channel processor). HP recommends configuring alternate paths for safer operation and increased bandwidth. For instructions, see Setting alternate paths for external LUs.
Page 28: Examples Of Switching I/O Execution Paths To Alternate Paths
Since two ports of different clusters must be set in the local array for External Storage XP to use alternate path settings, HP does not recommend the configuration shown in Figure...
Page 29: Alternate Path Mode Is Multi Mode
Figure 5 Alternate path mode is Multi mode NOTE: In Multi mode, active I/O load balancing occurs across external array ports and controllers. The XP and EMC DMX are examples of external arrays that use Multi mode. • Alternate path mode is Single mode Figure 6 shows an example of when the alternate path mode is Single mode.
Page 30: Alternate Path Mode Is Single Mode
Figure 6 Alternate path mode is Single mode • Alternate path mode is Single mode and at least one alternate path is in Standby status Figure 7 shows an example of when the alternate path mode is Single mode and there are alternate paths in Normal and Standby status.
Page 31: Alternate Path Mode Is Single Mode With Alternate Paths In Normal And Standby
Figure 7 Alternate path mode is Single mode with alternate paths in Normal and Standby NOTE: External arrays with Asymmetrical Active/Active (AAA) controllers, such as the Hitachi Thunder, are an example of Figure 7. A notable characteristic of using AAA controller arrays as external storage is that paths to alternate ports on the owning controller for a given external LU are seen as Normal status, but I/O load balancing does not occur (either across controllers or across ports to the owning controller).
Page 32: Powering Arrays On Or Off
Figure 8 Alternate path mode is Single mode with alternate paths in Standby only NOTE: External arrays with Active/Standby (A/S) controllers, such as the MSA, are an example of Figure 8. A notable characteristic of using A/S controller arrays as external storage is that there is typically only a single port to the owning controller.
Page 33 NOTE: To disconnect an individual LU, use the Disconnect Volume command. To delete a single external LU's mapping, use the Disconnect Volume command and then the Delete LU command. For instructions, see Deleting external LU mappings (Delete LU). • Check Paths & Restore Vol. This command checks if defined information about the mapped external LU and the actual external LU status match.
Page 34: Powering Local Arrays On Or Off
Powering local arrays on or off To power local arrays off CAUTION: When you want to turn off both the local array and the external array, you first need turn off the local array, and then turn off the external array. Stop read and write I/Os to the external LU that is mapped as a local array internal LDEV.
Page 35: Powering External Arrays On Or Off
Troubleshooting NAS Blade systems that include external arrays. Split all HP StorageWorks Business Copy pairs (pairsplit operation). For details on the pairsplit operation, refer to HP StorageWorks Business Copy User’s Guide. Turn off the power supply of the local array.
Page 36: Using Mapped External Lus From The Host Connected To The Local Array
Make sure that the power supply of the local array is completely on and then go on to the next step. Resynchronize all HP StorageWorks Business Copy pairs (pairresync operations). For details on the pairresync operation, refer to HP StorageWorks Business Copy User’s Guide.
Page 37 Mapping external LUs (Add LU). For open-system emulation types (such as OPEN-V, which HP recommends), the status of the mapped LDEV is set to Normal and is not automatically formatted. To optimally initialize the mapped LU's data area, use Volume Manager to format the mapped LU. For instructions, see the HP StorageWorks LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200.
Page 38: Using Existing Data In Mapped External Lus
Figure 9 Writing new data to mapped external LUs Using existing data in mapped external LUs Figure 10 shows an example of using existing data in a mapped external LU from the host connected to the local array. From the host connected to the external array, write data to the LU in the external array. Use External Storage XP to map the LU in the external array containing data as an internal LDEV of the local array.

Page 41: Ext. Lu Cap. Is Larger Than The Spec. Emulation Type's Basic Cap. (Open-3 Ex.)
LU capacity. Available capacity decreases by the size of the XP array management information area, and all prior data must be considered lost. For more information, see the HP StorageWorks Flex Copy XP user guide. Figure 12 shows an example where the external LU's original capacity is larger than (or a multiple of) the normal size of the local array's emulation type (OPEN-3 in this example).
Page 42: External Lu Capacity Is Smaller Than The Specified Emulation Type's Basic Capacity
• If you mapped a volume that has not been zero-formatted on the external array side, format the volume on the local array side. For instructions on the formatting and Write to Control Blocks operations, see the HP StorageWorks LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200.

Figure 18 Example of Snapshot XP operations Use External Storage XP to map a volume in the external array to an internal LDEV of the local array.
Page 54 The mapped volume's status automatically becomes Normal. However, the volume formatting processing does not execute automatically. To format the mapped volume, format the volume using the CVS function. For instructions, see the HP StorageWorks LUN Configuration and Security manager XP user guide for the XP12000/XP10000/SVS200.
Page 55: Managing Cache With External Storage
When you deviate from these workload descriptions, performance might not be as good as when cache is disabled. Consult your HP account support representative to discuss the availability of tuning services for your XP array.
Page 56: Determining, Setting, Or Changing The External Lu Cache Mode
Determining, setting, or changing the external LU cache mode You set the cache mode when you define external LUs. HP strongly recommends that you set cache mode to Disabled for external LUs. For instructions on mapping external LUs in a new configuration, Mapping external LUs (Add LU).
Page 57: Changing The Cache Mode
Figure 19 LU Operation pane, Cache Mode setting Changing the cache mode If you need to change the cache mode for existing external LUs, you must delete and remap the external LU path and definition. CAUTION: Before you delete any LUs that you want to remap, carefully record necessary configuration information. If you remap existing LUs with changed configuration settings (other than cache mode), you can lose access to the LUs and the data they contain.
