disk use

Fredy Correa — Tue, 27 Mar 2007 19:54:29 GMT

As I can know if a disk this being used by something???
if I give him the command ls - lart /dev/dsk shows me the disk c8d10t2, but if I give him the command diskinfo / dev/rdsk/c8d10t2 tells me that there is an error. I need to revise that not him this using anything to be able to erase it and to configure it again.
It is urgent,
Thank you,

You should note the the prescence of a device node (e.g. ls -l /dev/dsk/cXtYdZ or /dev/rdsk/cXtYdZ) actually means very little. It means that at one time (and maybe now) there was a device associated with this node but it means little more than that.

A better test is ioscan -C disk -fn. If you see "CLAIMED" associated with the device then that is a stronger indication. If you see "NO_HW" that indicates that there is a problem associated with the device.

clay is right... this might be problematic or stale device file... do a ioscan -fnC disk and reconfirm...

Hi,

Check whether the disk is getting amber light, get the out put of ioscan -fnC disk and confirm the disk is in good status run insf -e and try to get the diskinfo and check whether the problem repeats again if it repeats remove the volume group and recreate the volume group and confirm it is a harddisk issue.
