Hi,

I am having 2 volume groups rootvg (Only for os),datavg(only for data) both are from san using different LUN.

out of these my rootvg was crashed though I have reinstalled os.

can you please suggest me now how datavg will be visible, wheather I have recreate VG?

Kindly suggest me.

Hi,

just try to import the volumegroup

Code:

importvg -Ry volumegroupname hdiskname

for example:

Code:

# importvg datavg hdisk7

Kind regards
zxmaus

Thanks but I am getting below error.

# importvg -Ry datavg hdisk1
0516-066 lqueryvg: Physical volume is not a volume group member.
Check the physical volume name specified.
0516-066 lqueryvg: Physical volume is not a volume group member.

Hi,
does readvgda show you any output? Does your disk have a pvid assigned? What kind of storage do you use ?

You can try to remove the scsi reservation or you can try an importvg -f ...

while using lsvg command it is showing only one vg "rootvg". using lspv command for hdisk1 which was earlier datavg it showing like

hdisk1 0009999zzaae0a00 None

as os was crashed and I have cleanly installed frest os, from where it will get the information about datavg?

The information about VG is stored in the VGDA of the disk hdisk1.. so intsalling new OS wont erase this info from hdisk1 and now try this

Code:

importvg -y datavg -f hdisk1

zxmaus suggested you to run the following command and then please post the output of

Code:

readvgda hdisk1
