Sun StorEdge A1000 is one of the oldest storage array from SUN but still widely used. Just recently, we received a battery expiration and we need this replaced as soon as possible to ensure optimal operation of the said Sun StorEdge A1000 array. Below are the steps that we used to replace the expired battery:

Today we encountered a degraded policy in EMC PowerPath disk on one of our SUN/Oracle Solaris boxes. We found out that the license for our PowerPath was not properly installed on the system. 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.

Having a Mission-Critical Environment means a system downtime could mean a lot. Here comes the high availability comes in, and with clustering this give our service availability very high. In the upcoming Solaris 11, high availability is the main focus of Oracle. Solaris Cluster covers a lot of applications, zfs and virtualized zones.

We have already discussed on how to add an EMC storage to a Solaris box. Now we have a dead path on our system where the storage team has decommisioned. Here are the steps to follow on how to remove these dead paths from our system.

New task at hand fellow UNIX Administrators. Now we need to discover the new (EMC) LUNs presented by the Storage team and make it available into Veritas Volume Manager (VxVM) and extend one of the filesystem under Veritas Filesystem (VxFS).
