Extending File System used by Servicegaurd

[Keao]

We need to extend a file system on an Oracle server that employs the use of ServiceGuard. This file system is one of three that swing to the failover node when failover occurs. There aren’t any Free PE’s that would allow us to extend the current (full) file system without adding another LUN first.


My question is.... what is all that’s necessary to ensure that a newly created (and properly-sized) file system on a new LUN will be seen by both nodes in the cluster? Any information would be greatly appreciated.

Thank you,
Jon

Shalom Jon,

The SAN admin needs to look at the existing LUN and present the new one the same way and in the same zone. This will insure it is visible by both nodes.

ISSUES:
WWN of all involved fiber channel cards (fcmsutil will give it to you). LUN must be visible to all.


After presentation, you should be able to see it with ioscan. You might want to use insf -C disk, but be careful insf can reset disk devices to root ownership and you don't want that to happen with Oracle RAC.
