Verifying that the back-end configuration matches the intended configuration

After resolving the back-end configuration errors detected by storage errors show, you must check whether the existing back-end configuration matches the configuration you intended, and fix issues arising out of any mismatch.

Steps

  1. Enter the following command: storage array config show

    The storage array config show output groups information about LUN groups, LUN counts, and paths by storage array, as the following example for an HA pair shows:

    mysystem1::> storage array config show
             LUN   LUN
Node         Group Count  Array Name      Array Target Port   Initiator
------------ ----- ----- ---------------  ------------------  ---------
mysystem1a    0    10     DGC_RAID5_1      5005076303030124       1a
                                           5005076303088124       1b
                                           5005076303130124       1c
                                           5005076303188124       1d
mysystem1b    0    10     DGC_RAID5_1      5005076303030124       1a
                                           5005076303088124       1b
                                           5005076303130124       1c
                                           5005076303188124       1d

  2. Check the storage array config show output for each problem statement in the following table, and refer to the appropriate information for solution.

    If you find this problem…​ See this information…​

    Empty LUN groups

    Reasons for no LUNs in the array LUN group

    Missing expected storage arrays

    Reasons you might not see all storage arrays you expected

    More array LUN groups than expected

    Reasons for more array LUN groups than expected

    Fewer array LUN groups than expected

    Reasons for fewer array LUN groups than expected

    Array LUN groups do not show the number of LUNs expected

    Reasons for the incorrect number of LUNs in array LUN groups

    Fewer paths than expected

    Fewer than two paths to an array LUN

    More paths than expected

    Reasons for more paths to an array LUN than expected
