vgdisplay not showing data VG, even its lvs are mounted

[Reema1]

Hi,

I have a problem with vgdisplay. It is not showing application VGs but the filesystems are mounted using the VG.

appsserver:/homeroot/root> bdf /ORACLE/data5/TPWHPROD
Filesystem kbytes used avail %used Mounted on
/dev/vx/dsk/vgHAtpwhprod/lvtpwhproddata5
870318080 847883364 22084232 97% /ORACLE/data5/TPWHPROD
appsserver:/homeroot/root>
appsserver:/homeroot/root>
appsserver:/homeroot/root>
appsserver:/homeroot/root> vgdisplay -v vgHAtpwhprod
vgdisplay: Volume group "/dev/vgHAtpwhprod" does not exist in the "/etc/lvmtab" file.
vgdisplay: Volume group "/dev/vgHAtpwhprod" does not exist in the "/etc/lvmtab_p" file.
vgdisplay: Cannot display volume group "vgHAtpwhprod".

the server is running service guard and this VG is under service guard HA. 

is there any impact if I do "vgscan -N -f /dev/vgHAtpwhprod" on running server? I do not want to make any unneccessary outage.

Looks like VxVM, not LVM.

Try

# vxdisk list
