Re: LUN not showing in xpinfo command

It's in fact a LUN.

But is it still present and presented?

What does vgdisplay show for this VG?

Hope this helps!
Regards
Torsten.

Re: LUN not showing in xpinfo command

Hi all,

Thanks for your reply.

Check the requested commands output below.

root@ttd:>ioscan -fnC disk |grep c8t8d6

/dev/dsk/c8t8d6 /dev/rdsk/disk_query

/dev/rdsk/c8t8d6

root@ttd:>vgdisplay -v |grep c8t8d6

PV Name /dev/dsk/c8t8d6 Alternate Link

root@ttd:>xpinfo -il|grep c8t8d6

check the o/p of cu:ldev no below
root@ttd:>xpinfo -i|grep 03:dd
/dev/rdsk/disk_query 71 00 46 CL3E 03:dd OPEN-V 00072344
/dev/rdsk/c24t8d6 54 08 46 CL4E 03:dd OPEN-V 00072344

i got this cu:ldev no for primary path by vgdisply -v VGgrp name

Thanks,
chandra

Re: LUN not showing in xpinfo command

/dev/rdsk/disk_query could be a modification made by administrator.

I would like to see more command outputs, e.g. a full vgdisplay or at least the full line for this device from ioscan, not only these "greps".

Hope this helps!
Regards
Torsten.

Re: LUN not showing in xpinfo command

I found that

/dev/rdsk/disk_query

is a temporary file used by previous versions of SAM, this is fixed by a patch - is your patch level current? Likely not.

Hope this helps!
Regards
Torsten.

Re: LUN not showing in xpinfo command

There is still no vgdisplay attached ... as mentioned before: Consider to patch your system first!

The disk_query device should NOT be listed.

Hope this helps!
Regards
Torsten.
