    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...

    For more information about path status, see ”Adding alternate paths by selecting multiple external LUs (Add Paths)” on page 89. • Alternate path mode is Multi mode Figure 5 shows an example of when the alternate path mode is Multi mode. When an error occurs in one path, I/Os execute using paths other than the error path.

  • Page 25: Alternate Path Mode Is Single Mode

    NOTE: As you restore the path with a priority higher than the current path, the I/O execution path automatically switches to the restored path with the highest priority. 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 26: Alternate Path Mode Is Single Mode With Alternate Paths In Normal And Standby

    NOTE: When the external array is an EVA array, as you restore the path with the highest priority, the I/O execution path switches back to the restored highest priority path. In this case, the status of the path for which the status changed to Normal when the error occurred changes back to Standby.

    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.

    This command checks if defined information about the mapped external LU and the actual external LU status match. If the external LU can be used as the mapped local array volume, the external LU is set to accept I/O, and you can continue using the external LU as a mapped LU. Use this command to restore the external LU, which is set to reject host I/O operations by the Disconnect Subsystem or Disconnect Volume command, as the mapped volume.

    Continuous Access XP P-VOLs, S-VOLs, and journal volumes are not supported on MSA arrays. • HP does not recommend that volumes involved with Snapshot XP reside on external MSA arrays. • If you map an external LU that is more than 2 TB with the setting of OPEN-V emulation type, you can access data stored in the field up to 2 TB.

  • Page 33: External Lu Capacity Is Smaller Than The Specified Emulation Type's Basic 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).

In this case, two different logical volumes with the same name, such as LUN 1 and LUN 2, are found as logical volumes that can be connected from EVA Port A, but you can only tell which LUN 1 and LUN 2 belong to HostGroup-1 or HostGroup-2 by examining the Characteristic field.

    NOTE: You must select external storage LUs through the presenting controller. Failure to do so results in new external LDEVs being placed in a blockade state shortly after a host attempts to access them. Figure 72 Selecting EVA LUs After you select an external logical unit (LU), the Add LU pane appears. At this point, you can configure each individual external LU by choosing options such as the emulation type, the number of LDEVs (CVS is used), and the LU’s unique LDEV identifiers within the XP12000/XP10000/SVS200.

    EVA3000/5000 models have two ports per controller) than a similar configuration with an MSA (only one port per controller). In spite of this, HP strongly cautions you to carefully weigh the financial cost of a dedicated XP12000/XP10000/SVS200 external port versus the benefit of any added EVA external storage performance.

    Troubleshooting • Be careful to define an external storage LDEV presented to the XP12000/XP10000/SVS200 by the EVA from the EVA controller that is presently serving its associated LU in an active status. • If you attempt to define an LDEV from an LU via that LU’s passive controller, the resulting external storage LDEV is placed in a blockade state.
