disk paths

[Vogra]

Hi All!
I have some lvols and I need to remove some. I want to know in wich disk the specific lvol is. How can I do that? Thanx.

Hi Claudio:

# lvdisplay -v /dev/dsk/lvolX

...will show which physical disks have logical extents for the logical volume in question.

Regards!

Example :

# lvdisplay -v /dev/vg01/lvol2 | more

Of course in a volume group with multiple disks, you could have lvol's that are one more than one disk, and multiple lvol's can be on a disk.

The first step is to delete (remove) the lvol's you want to remove, then using vgdisplay -v vg## | more (where ## is the volume group number) to see what disks are in your VG. Then using the pvdisplay -v /dev/dsk/name | more (where name is the disk device, like c5t2d0) to see if any lvol's are still using the disk.

Hi,

Try this:

1) find out which LV's you want to remove.
2) Unmount those file systems ( umount /fs1)
3) Find out LV information ( lvdisplay -v /dev/vg01/lvolx )

In this check the PV names and path to determine the hard disk details.
4) lvremove lvname
5) Remove entries from /etc/fstab.


Also, the specific HDD can be part of other LVs too. For a specific HDD info, do 'pvdisplay -v /dev/dsk/cxtxdx'

HTH,
