NSS device/partition ID's8/20/2008 3:36:02 PM

Should my Device ID's and Partition ID's as shown in NSSMU be the same
across cluster nodes?

I'm experimenting with a NW6.5 cluster. When i add a new LUN on the
san, a "cluster scan for new devices" does not pick up the new luns.
Should it? If i do an F2-Scan in NSSMU on each node, it does find the
new LUN. But the device id is different on each node. Partitions
created also have differed id's. Is this normal or should i be
concerned?

Device ID's will be. Not sure on Partition ID's just do not pay attention
to them.

The Device ID looks like this:

V597-A4-D3:8 - The A4 in this case is the adapter. If you have multiple
HBA's it can be different using the native NW multi HBA support (sorry
forgot the name of it).

To make more sense of them use Novell Remote Manager -under Manage the
Server -is Partitions and Volumes, there you will see the 'symbols' for the
device (a SAN LUN), the partition, pool and volume. Once you get use to it
there -head to NSSMU and you will have better luck reading it.

Since you are experimenting -here are a few articles that might help you
understand it better:

Good Luck -you'll love clustering!

Gregg, thanks for the info. By device id, i actually meant the hex
number on the left side in NSSMU. I have a device A2-D1:2 that both
nodes can see. However one on node, the device id on the left is "0x6B"
while on another node it's "0x6E". The are in fact the same LUN on the
SAN though. These hex id's only seem to be useful in nssmu, so i'm not
sure if it's normal that they're different between nodes. Thanks.

Yeah I believe (not positive though -would have to see it) they will be
different per node. As long as the info to the right tells you the same
thing on both nodes you will be ok. That's why I pointed you to Novell
Remote Mgr (http://ipaddressofserver:8008) because it gives a clear picture
without the confusion of converting hex.
