Re: Identifying vdisk from host mount point
speaking for HP-UX:
run strings /etc/lvmtab | grep
to make sure you have removed/exported all VGs that used any path/device file to the lun
then
remove the presentation to the UX host and
run ioscan -fnCdisk and will see "NO_HW" on all the paths to the LUN.
the paths will disappear after the next reboot (which is not required).
Regards,
Bernhard

Re: Identifying vdisk from host mount point
in HP-UX you have ioscan and fcmsutil/fcdutil.
ioscan -fnkCfc
will list FC HBAs
depending on the HBA you have /dev/td# or /dev/fcd# device files
you can run
fcmsutil /dev/td# get remote all
or fcdutil /dev/fcd# get remote all
also in ioscan -fnkCdisk the last number in the HW path represents the LUN# HP-UX wise.
Regards,
Bernhard

SolutionLet's say vdisk_001 is LUN 6 and vdisk_002 is LUN 17.
The LUN numbers will be the scsi addreses to the hosts. I can't remember exactly where to find this on windows. I know it is in the disk manger, properties, somewhere.
On HPUX it is coded in the device file.
/dev/dsk/cXtYdZ
LUN numbers less than 128 just multiply the 'Y' by 8 and add 'Z'
eg. c10t0d6 = 0 * 8 + 6 = LUN 6
c10t2t1 = 2 * 8 + 1 = LUN 17
if the LUNs are too big you need to extract some bits from the 'X' and multiply it by 128 or 256, don't remember and that gives you the LUN number.
If you need that reply back and I'll look up the details. Same for windows.
BTW, If you are using securepath, you'll need to do this with the hsx devices shown when you do the spmgr display.
