Server with 2 VA7100

I have an N class server with 2 VA7100 attached. I've recently removed some filesystems which has freed up a few LUNs. I need to delete these LUNs to increase the free space on the array, but I'm having problems trying to identify them. The problem is that the LUN numbers (numbered 29 thru 35) exist on both arrays. The output from armdsp -c only tells me the port id's (not a hardware or device address as on a va7400) and the port id's are the same on each array for each controller. Any ideas how I can work this out, or would I have to track the cabling from the array?

Re: Server with 2 VA7100

You could use both the hardware path and the output from 'fcmsutil /dev/td0 get remote all' To figure out which va is on which Nport based on the wwn.

Yes, the output of the tdutil /dev/tdX command will tell you what Nports can be seen. Then in the armdsp -a command you can find out what controller has which Nport.

Re: Server with 2 VA7100

try "armdsp -a your_array_alias" and you will
see the Management Path like

Management Path: alias:/dev/dsk/c8t0d0

so you have an idea of the device files.

Hope this helps!

Re: Server with 2 VA7100

The VA7100 doesn't display a hardware path or device path - only the VA7400 does this. The output from fcmsutil doesn't match up with the output from armdsp - the port id's are all different. Any other ideas?

Re: Server with 2 VA7100

Are your VAs directly connected?
Perhaps I know what you are looking for.
The output from
tdutil /dev/td0 get remote all
should deliver the WWN of (direct) connected devices. Compare these WWN-values with output from armdsp -a ... and you will know which VA is connected to which HBA (/dev/td0 ...)

Hope this helps!

Torsten.

Re: Server with 2 VA7100

Sorry, not reading the replies correctly! Yes, a fcmsutil or tdutil get remote all does tally with the WWNs of the arrays.

Many thanks.
