Serviceguard Oracle and VC

[lynx_deb]

Hi,

we have 2 BL870i (each server in a different C7000 enc) in cluster with Oracle DB 11 installed, the storage is an XP24000 and filesystem is Vertitas Enterprise (but without clustered option enabled). Recently we have install on the C7000 enc where is located the second node 2 VC Flex-10 and 2 VC FC-8Gb. The VC are configured with WWN/MAC assiegned by VC and not the native. Now.. before this "modification" we were able to switch the package from node1 to node2 and node2 to node1.

Yesterday we have tried to switch to node2 to install the second pair of VC on the other blade, but the second node doesn't activate the VxVG. We have controlled zone mapping (because the WWN are changed) and all is right, also the second node see all the disks path of the node1 (but with different disk number, may be this is the problem?), but Veritas seems to not found the VGs to deport on the second node.

Also on the second node, if I do a "vxdisk list", there is only the internal disk of the machine and not the VG (is it right when the VGs are active on the primary node?).

Could be possibile that a change of WWN (and may be disk number name) on the machine has made Veritas to loose all the information about disks on second node?

I attach the cluster log from the second node.

thanks!

What did you have before the VC modules. Were the VC modules added in addition to the pass through modules that were in the enclosure before or did they replace the pass through modules with VC.

IF you replaced pass through modules with VC of course you need to reconfigure everything since your MAC addresses could have been assigned to VC and your vlans need to know about this.

Your serial number of the blade could be assigned by VC and your WWID of the FC cards are now assigned to VC and not the original ones in the blade.

YOu need to goto your san guys and present the luns to the new WWIDs or zone the switch for the new WWIDs so your system sees those disks.

You could decide not to do this and not "virtualize" the MAC and WWIDs but you loose the quick replacement of a blade functionality with the same WWIDs and MACs that VC provides.

Before VC, we had 2 Gb2e and 2 4GB pass-thru

we have already remapped new WWN on the XP24000, the second node already see the same LUN of the primary node..

but VX doesn't see the VG...
