Help mapping storage on HP/UX to SAN

[Mike Keneipp]

I am trying to map from the file systems and disks I see in hp/ux to the information the SAN admin can use on his end, so we can look at usage vs. allocated space on the various systems. I can get the info from the file systems, logical volumes, volume groups, and physical volumes, but that information doesn't help him any. I thought I could go from the ctd to the SAN lun or a world wide id, but the problem I come across is that I find far more luns on my side than he is presenting on his.

If it helps/makes a difference, I'm on an HP/UX 11.11 system, and connecting to an EVA 8000.

Thanks in advance,
Mike

shalom,

ioscan -fnC disk
# get the device names of the disks.

pvdisplay

# Returns the logical volume names

lvdisplay

# Displays the free and allocated space on each logical volume by PE.

This assumes the disks have been assigned to the system. IF not assigned, you need to use the controller for the EVA-8000 to check this information.

Mike,

You need evainfo:

You'll probably see each vdisk on the EVA 4 times (once for each port on the EVA), so don't worry about that difference.

evainfo will show you the WWID of each disk on the HP-UX host. Your SAN admin should thgen be able to relate those back to vDisks in Command View EVA.

If you want to go one step further then you should also get hold of a copy of sssu for HP-UX - with that you can talk direct to the Commandview EVA instance from HP-UX and pull out the configuration. It's relatively simple to create a script which uses the output of evainfo and sssu to relate disks on a system (ctd) to vDisks on the EVA. There's not really an easy way to download sssu though. There is usually a copy on the Command View EVA installation media if you can lay your hands on that.

Hi , Mike,

Its better to use EVA 8000 command view , to look the usage vs. allocated space on the various systems

Example :-
Information like how much have you presented LUNS to various system
current usage of your LUN and many more,

Thanks,
Johnson
