  • Page 22: Alternate Paths

    If you have not configured any alternate paths, host I/O operations are suspended when the primary path becomes unavailable (such as during disk array maintenance operations or following a failure in the channel processor). HP recommends configuring alternate paths for safer operation and increased bandwidth. For instructions, ”Setting alternate paths for external LUs” on page 74.

    NOTE: When the external disk array is an EVA disk 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 disk 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 disk arrays as external storage is that there is typically only a single port to the owning controller.

    This command verifies that the saved information about the mapped external LU matches the actual external LU status. If the external LU can be used as the mapped local disk array XP LDEV, the external LU is set to accept I/O operations, and you can continue using the external LU as a mapped LU. Use this command to restore host I/O operations to a mapped external LU after disabling those operations using either the Disconnect Subsystem or Disconnect Volume command.

  • Page 29: Turning The External Disk Array's Power On Or Off

    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.

    LU. This means that the capacity available after mapping is slightly smaller than the actual external LU capacity. Available capacity decreases by the size of the XP array management information area, and all prior data must be considered lost.

Because the OPEN-V emulation type supports a maximum of 2TB of the volume, one LDEV is always created when the external LU is mapped. If you use the Volume Manager function, you can divide the mapped external LU into a maximum of 256 CVs.

    NOTE: To create a Continuous Access XP pair with a volume of an XP1024/XP128 disk array, you might not be able to create a CV with the same capacity as the internal XP LDEV (B) because Volume Manager does not allow you to specify the capacity in blocks. In this case, you cannot create a Continuous Access XP pair.

    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 61 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.

    Troubleshooting • Be careful to define an external storage LDEV presented to the XP12000 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.

If you request only the exact size needed, the ACU optimizes the LU to a size of 40959 MB, which is 1 MB smaller than needed. In this case, the optimization algorithm the ACU uses can be compensated for by specifying a size of 40963 MB, which results in the correct size of 40960 MB (40 GB).
