Re: Checking multipathing on hpux v3

Shalom,

Multi-pathing is built into the 11.31 OS.

ioscan -fnC disk should show it.

To have two paths show up, there needs to be two paths to the disk.

This may vary by server type, but there is normally one path to the built in disks, in say an rx6600

Re: Checking multipathing on hpux v3

Several ways to get this, try

# ioscan -m dsf

and count the "old" device files for e.g. disk118

Hope this helps!
Regards
Torsten.
