adding new disks

Ravinder Singh Gill — Thu, 20 Oct 2005 04:42:44 GMT

We have added new disks to a server. I have already performed insf -e on them. Is the pvcreate supposed to be performed after insf -e? (not before?)

Have you done #ioscan -fnC disk ?

pvcreate is after insf -e

-e Reinstall the special files for pseudo-drivers and existing devices. This is useful for restoring special files if one or more have been removed.

hi,

yes, use insf to install the device file before using "pvcreate -f" to force create the physical volume (which delete content of any file system). u need the device file for pvcreate command.

Hi,

Actually HP-UX will automatic create a device file for your new disks; but if this not happened, you can run :

# insf -e -H

And after that, you can run pvcreate to create physical volume foruse in LVM volume group.

Check this url below for your reference :

Hope this information can help you.

Cheers,
AW
