Re: defining how much spare in hp-ux
Hi,
>> how much spare disk is available to epand the following filesystems:
You can use vgdisplay -v vg01 command to find out Free PEs.
Total available space in vg01 would be Free PEs x PE Size (Mbytes)
Morover, you can use ioscan -kfnC disk and pvdisplay command to find out total free disks available to your system to extend your VG.
>> how to confirm if the physical disks (spindles) used by
# strings /etc/lvmtab
OR
# lvmam -l (If using 11iv3)
Regards,
Dave

Re: defining how much spare in hp-ux
This is still the favorite topic of dba's!
As suggested, do
# strings /etc/lvmtab
and
# vgdisplay -v vg01
# vgdisplay -v vg02
to see what PVs are involved.
Do also
# lvdisplay -v /dev/vg01/lvol2
# lvdisplay -v /dev/vg02/lvol1
and finally
# ioscan -fn
to get informationen about the disks.
Nowadays these are often LUNs in the SAN, so you can often be sure it is using many, many physical drives, but this depends on the array model.
Hope this helps!
Regards
Torsten.
