Hi, This may end up as a double post as my first attempt appears to be caught in limbo so my apologies now if that is the case. I¹m currently in the process of setting up a 2 node cluster but have run into a few problems. The nodes are in different sites running RHEL3 AS and connected by fibre to EMC Clarion arrays with PowerPath doing the multipathing - the cluster software being used is Legato AAM. The arrays are running MirrorView to replicate the data between each array with one a primary and the other a secondary. At the moment I can attach the luns to the first node and mount the ext3 filesystem, but when attempting to failover to the secondary node I¹m unable to mount the filesystem if the secondary node is rebooted it can then mount the filesystem. I think this may be related to how MirrorView manages the primary and secondary arrays. For example if the primary node is active the secondary node is unable to access the lun. So when failover occurs I don¹t believe the secondary node has the luns loaded into the kernel, which means I need to somehow rescan the luns before they can be mounted (I guess the equivalent command in Solaris would be devfsadm). Does anyone have any ideas whether this is possible and how I would go about doing it? Thanks for you time.
