modify the disk status to online in veritas volume manager

To All,

We have Veritas Volume Manager 3.1 which is installed in HPUX 11. Our external storage(SC10) used that to configure RAID 5. Recently, RAID 5 have been in degraded status. We have verified from Veritas that one of the disk is in error and failed status.The disk has two device name because it has an alternate link. From HPUX side and light indicator from SC10 that disk is not defective. Please provide us command to modify the disk status to "online".

I attached the screen shot of listing of disk to help you visualize our concern.

Thanks.

Adriatico

SC10 is attached to a SCSI adaptor or RAID controller?
Verify the disks with diskinfo /dev/rdsk/cxtxd0
and dd if=/dev/dsk/cxtxd0 of=/dev/null

Looking at the LED status may not be correct always!

see man page of vxdisk before trying below

vxdisk -a online
vxdisk online

Regds

SC10 is only attached in SCSI controller and to achieve high availability we used veritas volume manager.

Using dd to verify disk is successful. Therefore, the disk is not defective.

I could not see an online options from vxdisk command.

Hi,

If you are sure of the disk is fine, then you may re-initialise the disk for VM.

Use vxdiskadm or vxdiskadd.

There is also "vxdisk online accessname" command which would make the disk online.

Try vxdisk -H to get all the available options.

Regards

Adriatico,

I believe you should use the vxdctl command to let the OS/vmsa now the disk is back online.

# vxdctl enable

Hope this helps,
