Change EMC Powerpath Failover Policy on UNIX Systems

As UNIX system administrators – we need our Operating Systems running in optimal state every time. The same is what we want to our storage systems. In EMC Powerpath there are a couple of failover policies that we can enforce to our storage devices but we must always use the one that is best suitable.

Import Disk Group (DG) in VxVM

Have you ever encounter rebooting a server and your Veritas filesystems are missing? Most cases these filesystems were not imported during boot up and is not available for OS to use. Importing a disk groups in VxVM does not need any reboot, follow these simple steps and you will be able to get back your disk groups in no time.

With this current issue – our disks is only running on Basic Failover policy which is not recommended for CLARiiON disks. To mitigate the issue, we need to install the license and set the policy back to CLARiiON Optimization Policy.
