output of storage subsystem

Hi,

I am looking for a script that maps the volume groups, logical volumes, physical volumes, sizes and raid information.

Appreciate a response.

thanks

Man on lvdisplay says
"Mirrored disk information requires the installation of the optional HP
MirrorDisk/UX software, which is not included in the standard HP-UX
operating system."

Is there any other way to find out if volume group has mirrored disks besides using sam?

Yes, you can use the lvdisplay command:

# lvdisplay -v /dev/vg00/lvol1

Look for "Mirror Copies" and that will tell you if you have mirroring on that logical volume and how many. If it's 0, then that LV is not mirrored.

For the original question: You may try the print_manifest command (if Ignite-UX has been installed on your system) and that should give you some similar outputs:

# /opt/ignite/bin/print_manifest
