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:
    Example
    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
