    All;

    Recently I created a couple of new vdisks on our EVA5000 and presented them
    to our 4 node GS1280 cluster running Tru64 5.1b PK4. I used hwmgr to
    refresh the components and then saw the 2 new devices in the "hwmgr -v d"
    output. All looked as it should. I then renamed the device special files
    via "dsfmgr -m <old device> <new device>. The normal messages appeared on
    the screen and the command completed successfully. The <old device> files
    no longer exist in /dev/disk and the <new device> files exist in /dev/disk.
    However, "hwmgr -v d" does not report the correct info. Here's a snippet of
    the output from the "hwmgr -v d" command:

    > 1345: /dev/disk/dsk12717c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12717
    > 1865: /dev/disk/dsk12801c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12801
    > 1876: /dev/disk/dsk12900c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12900
    > 2113: /dev/disk/dsk12720c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12720
    > 2114: /dev/disk/dsk12721c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12721
    > 3249: dsk22410 COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12722
    > 3250: dsk22411 COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12723
    > 3251: /dev/disk/dsk22412c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12582
    > 3252: /dev/disk/dsk22413c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12583

    the 2 problem disks are dsk22410 and dsk22411. When I first created and
    presented the disks they looked like all the others above in that the
    output showed /dev/disk/dsk22410 and /dev/disk/dsk22411. In other words, it
    looked like:

    > 3249: /dev/disk/dsk22410c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12722
    > 3250: /dev/disk/dsk22411c COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12723

    Then I issued the following 2 commands:

             # dsfmgr -m dsk22410 dsk12722
             # dsfmgr -m dsk22411 dsk12723

    after which the "hwmgr -v d" output changed to:

    > 3249: dsk22410 COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12722
    > 3250: dsk22411 COMPAQ HSV110 (C)COMPAQ IDENTIFIER=12723

    I'm guessing that perhaps the hwmgr database is confused. Would verifying
    the dsfmgr database (dsfmgr -v) be worthwhile or applicable? I presume that
    a reboot would resolve this issue but was wondering if there was some way
    short of that to get hwmgr to reflect the correct info.

    TIA.
