Quorum and hdisk issue
Hi. I found an issue with my appvg present in my server.my server is a single node and not part of hacmp.
Code:
pmut3# lspv
hdisk0          00c5c9cf92ebb96a                    rootvg          active
hdisk1          00c5c9cfcf30eee9                    appvg
hdisk2          00c5c9cfcf30ef98                    appvg
hdisk3          00c5c9cfba868e2c                    rootvg          active

Code:
pmut3# lsvg -o
appvg
rootvg

Code:
pmut3# lsvg appvg
0516-034 : Failed to open VG special file. Probable cause
is the VG was forced offline. Execute the varyoffvg and varyonvg
commands to bring the VG online.

The below mentioned 2 filesystems(/websp and /opt/websp) are present under appvg

/dev/fslv06 5.00 1.92 62% 4491 1% /websp
/dev/fslv07 10.00 4.20 58% 37905 4% /opt/websp
Code:
pmut3# lslv -m fslv07
0516-034 : Failed to open VG special file. Probable cause
is the VG was forced offline. Execute the varyoffvg and varyonvg
commands to bring the VG online.

Code:
pmut3# lslv -m fslv06
0516-034 : Failed to open VG special file. Probable cause
is the VG was forced offline. Execute the varyoffvg and varyonvg
commands to bring the VG online.

I guess there is something wrong with the hdisks present under appvg.

Can someone tell which hdisk(hdisk1 or hdisk2) under appvg is having a problem ?
Also what should I do to fix this quorum issue ?

Please let me know if you need the output of any commands from this server. I have informed the application team that
I need downtime to fix the issue in this server and I'm waiting for their reply. I'm afraid that I may loose the data present under appvg.
