How to increase size of a VXFS in VCS solaris cluster

Created: 09 Nov 2012 • Updated: 04 Dec 2012 | 3 comments
This issue has been solved. See solution.

Are these the steps:

1)Ask storage team to present LUN's

2)LUN's get presented

3)NOTE LUN's from top of format output

example: c7t50060161106023B8c43

4)run devfsadm on all THREE nodes

5)LABEL Luns using format utility(NO NEED TO PARTITION LUN's) 

example: format c7t50060161106023B8c43

6)Run vxdctl enable on all THREE nodes

7)Use vxdiskadm to initialize the LUN

disk to initialize: c7t50060161106023B8c43

8)Use vxdiskadm to add LUN to diskgroup

disk to add: c7t50060161106023B8c43

9)use vxresize to increase size of VxFS  (vxresize -F vxfs -g <vol group name>  <volume name> +Xg)

 

Questions: Will the disk name change after I do a vxdctl enable? Do I need to get VxVm disk names?

Your steps are fine and can be performed on the active node.

About VxVM disk name: it all depends on your current disk naming scheme.

What does 'vxdisk list' show?

Well currently vxdisk list shows disk names in CxTxDxSx format, not in c7t50060161106023B8c43 format

 

second question: one SG is online on one node and another SG is online on another node. I have to increase size of filesystems belonging to both SG's, do I need to go to each node and do this or can I do it from one node?

c7t50060161106023B8c43 is cXtXdXsX format (you're just missing the dXsX parts)

The resize needs to be done on the node which has the filesystem mounted.

Basically in your procedure:

Steps 1, 2, 3, 4, 6 need to be done on all 3 nodes.

Steps 5, 7 only need to be done once, can be done on any node.

Step 8, 9 need to be done on the system where the diskgroup and filesystem are online.

So if SG1 is running on node1, you run steps 8, 9 on node1. If SG2 is running on node2, you need to run steps 8, 9 on node2, they can't be done from node1.

Hope that helps.

Also: moved this to the Storage Foundation forum rather than the Storage and Clustering Documentation forum.
