LUN removal in Solaris 10 10/09 with VxVM 5.1

Hello,

I was assigned the removal of 86 unused LUNs in:

It's been a long time since I worked with VxVM 5.1, but remember that when we see disks like online thinrclm in that version, we needed to implement a special procedure to eliminate first the subdisks (something like reclaim).

    If all the LUNs in a given diskgroup (example SRP400dg) are unused, the you can just destroy the diskgroup using:

    vxdg destroy SRP400dg

    If some LUNs are still required, then to delete an unused LUN, then use for example:

    vxdg -g SRP400dg rmdisk SRP400_16

    But LUN will need to be unused and empry, so if it contains an unused volume then you need to delete volume or if there is an unused plex (mirrror), then you need to delete plex.

    Once LUN is removed from diskgroup (or diskgroup destroyed), you can the remove LUN at the SAN level to reclaim the space.

    Hello Mike,

    Thank you for the heads up.

    Did the below procedure procedure:

    How to remove a disk (thin reclamation - thinrclm) from a diskgroup when VxVM vxdg ERROR V-5-1-552 Disk  is used by one or more subdisks is reported.

    https://support.symantec.com/en_US/article.HOWTO58923.html

    Now LUNs will be unmaped and the OS cleaned up

    Thank you!
