On this post we will take a closer look at this veritas volume manager error when trying to display the available disk space in an existig datagroup. The error is “VxVM vxassist ERROR V-5-1-5455 Operation requires a disk group”

This is a draft post as I currently have no answer yet.. Weird thing is, the vxassist command works on one server and not in the other.. which is spitting out the error in subject.

Take this example:

Working server:


# vxdg list
NAME STATE ID
datadg1 enabled 1169455228.81.sgtjcpb1
datadg2 enabled 1169455429.95.sgtjcpb1
# vxassist -g datadg1 maxsize layout=concat
Maximum volume size: 390506496 (190677Mb)
# vxassist -g datadg2 maxsize layout=concat
Maximum volume size: 676767744 (330453Mb)
# vxassist -g datadg1 maxsize layout=raid5
Maximum volume size: 270483456 (132072Mb)
# vxassist -g datadg2 maxsize layout=raid5
Maximum volume size: 375160832 (183184Mb)


Looks fine right? But when I tried the same syntax on the other sever, I got this:

# vxdg -g sysdg free
DISK DEVICE TAG OFFSET LENGTH FLAGS
sysdg05 emcpower5s2 emcpower5 16777216 2029952 n
sysdg06 emcpower3s2 emcpower3 16777216 2029952 n
sysdg07 emcpower4s2 emcpower4 167772160 2020352 n
# vxassist -d sysdg maxsize layout=concat
VxVM vxassist ERROR V-5-1-5455 Operation requires a disk group
#


I suspect it has something to do with the Veritas VX version or the OS it is running. Will investigate further and let you know.
