depends upon what you using,
if power path
powermt display dev=XXXX

would show u...

if nothing just normal LVM then do a
vgdisplay -v vg_which has this disk

you would see the alternate disk marked with alternate disk.

Hi Bharat,

This depend on the type of storage and OS version you are using. In case of HP-UX 11.31 you can use
#ioscan -m dsf

Above command will show you the persistant path & all the legacy paths which are the alternat path of that disk.

In case of EMC storage you can use EMC power path software & can use the command
# powermt display

In case of HP Storage & HP-UX 11.23 or below you are supposed to use auto path or secure path software for load balancing & can use the coomand below to see the alt path to the disk.
# autopath display

Thanks

If not on 11.31 then SAM will show you.

If you do not have hell lotta disk....only c number would change tand d would remain same for the disk.
You can make out from there I suppose.

What OS version are you running, what type of storage are you using? Fiber or SCSI?
