Disk failure
Hi,
Hp-UX 11.00 on a D380 server.
One of the disks used by a LV is failed. But the failed disk might not have any data for the LV. There is no backup of the LV.
Is the removal of the disk from the LV & VG can help recovering the LV.?
Please tell if there any other ways of recovering the LV.
Thanks
John Jayaseelan

Re: Disk failure
lvdisplay -v /dev/vgXX/lv_name |more
for each LV on this VG.
It will show you which PV have data on it.
if no data is no your failed disk, use
vgreduce vgXX /dev/dsk/cXtYdZ

Fred

Re: Disk failure
Thanks for your reply.
I think 'lvdisplay -v ' displays all the PV used by the LV, But how to find the used PV has data or not.
Is it possible to recover the LV from other disks excluding the failed disk, even if there any data on the failed disk?
Thanks

Re: Disk failure
--- Distribution of logical volume ---
in this one, you will see wich PV are used for this LV.
using the command for each lv of the vg, you will have all actually used pv.
...
But since my first answer, I think of a simplier thing (I'm not 100% woke up in the morning) :
using "vgdisplay -v", you will see how many PE is used on each PV. If all PE are free on a PV, you can reduce the VG from this PV without any problem.
Regards,
Fred

Re: Disk failure
if one of this tree are true :
. None of lvdisplay -v shows your PV
. vgdisplays -v says as many "Total PE" than "Free PE"
. pvdisplay -v displays all PE as free
then you can use vgreduce

Fred

Re: Disk failure
The PV is not shown on the distribution list of 'lvdisplay -v' but it was listed on the details list with '???' instead of the failed disk name.
The failed disk is not displayed on 'vgdisplay -v'.
Thanks
