SAN attachement of RH5.4 Enterprise Linux Server

[nyck]

Hello,

I have a RH5.4 server that I'm SAN attaching to our CX300, on the RH server I have now installed Navisphere & PowerPath and have now been able to mount a LUN from our CX300:-

powermt display dev=all
Pseudo name=emcpowerb
CLARiiON ID=CK200043600821 [LONLIN5]
Logical device ID=60060160901012003E9EB8CB8EDADE11 [LUN 11]
state=alive; policy=BasicFailover; priority=0; queued-IOs=0
Owner: default=SP A, current=SP A Array failover mode: 1
==============================================================================
---------------- Host --------------- - Stor - -- I/O Path - -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
4 qla2xxx sdd SP A1 active alive 0 0
4 qla2xxx sde SP B1 active alive 0 0

The question I have is a bit daft but when we first started playing round with doing this yesterday we mounted a LUN up but the Pseudo name was emcpowera. I then removed this and bounced the server and then re-allocated the LUN and now its emcpowerb. Can someone tell me why this is the case?

I would like it to be emcpowera as it looks better!

Cheers

Nick

How did you remove the emcpowera?

It seems that you didn't run:

powermt release

Have a look here for the procedure:

I must admit that I just removed the LUN from the SAN and then bounced the RH server.

Then when I did it the second time I removed from the SAN and used the following syntax:-

powermt remove dev=<dev_name>

Then rebooted the server.

I will check the link when I get into the office tomorrow morning.
