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).

Extend Filesystem under VxVM
We have already discussed extending a filesystem in AIX under JFS as well as the basic of softpartion where we could also extend its filesystem size. This time we have a task which is under Veritas Volume Manager (VxVM). We need to extend a partition that is being managed by VxVM.
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.
Mirror Root Disk with Solaris Volume Manager (SVM)
As UNIX Systems Administrators, we want our systems up and running – 24 hours a day, 7 days a week. Though this could be achievable with the UNIX Operating Systems, we cannot set aside the fact that our hardware equipment are prone to wear and tear. One notable point of failure if our root or boot disks. Once it dies out – our only way is thru our backup and restore it. But there is another way that we could prevent this – if we have a spare identical disk as our root disk. We can have a redundant machine by having our root disks mirrored and make our system much reliable and omit this point of failure. Here are the step-by-step how to guide in mirroring our root/boot disk using the Solaris Volume Manager (SVM).
Remove EMC Dead Paths on Solaris
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.
Grow filesystem under VxVM
We have already discussed extending a filesystem in AIX under JFS as well as the basic of softpartion where we could also extend its filesystem size. This time we have a task which is under Veritas Volume Manager (VxVM). We need to extend a partition that is being managed by VxVM.
Solaris Volume Manager (SVM) Soft Partition Basics
Solaris Volume Manager (SVM) formerly called as Online DiskSuite and Solstice Disk Suite (SDS) is a volume manager that comes with the standard installation of Solaris 8, 9, and 10. But soft partition functionality was not included on the first release of SDS on Solaris 8, but it could be added with patch 108693-06 (latest). Upon introduction of Solaris 9, soft partition is included in SVM as one of it’s functionality.
How to Extend Filesystem on AIX using JFS
We are now going to discuss extending a filesystem under JFS on AIX machine. It is really pretty simple, actually in just 3 commands (including the checking) we could easily extend an AIX filesystem. But for the benifit of everybody, I would include extra checking and commands for us to fully appreciate this task.
