VxVM disk private regions show up as disabled while disk is reported online

[Ralph Grothe]

Hi,

sorry for misusing the LVM category,
because this is a Veritas Volume Manager question.
But it is yet another LVM, and even one that is shipped with HP-UX 11i.

We realized that there appear several vxvm disks that are reported as being online and enabled, as well as the plexes and volumes from the disk groups of these disks.
So everything looks pretty normal.
However when listing a detail report of these disks there show up private regions marked as disabled.
Now we wonder if this is normal behaviour (viz. a feature), or an indicator for a prevailing disk damage.

# vxdg list
NAME STATE ID
rootdg enabled 1061452959.1025.spree5
vgkp1a enabled 1061459695.1132.spree5
vgkr1 enabled 1061454921.1089.spree5


# vxdg list vgkr1|grep disabled

log disk c3t0d11s2 copy 1 len=451 disabled
log disk c3t0d13s2 copy 1 len=451 disabled

let's for instance take the first in the list of disabled above
