Server Model: T5120 with 146G x4 disks.
OS: Solaris 10 - installed on c1t0d0.
Plan to use software raid (veritas volume mgr) on c1t2d0 disk.
After format and label the disk, still not able to detect using vxdiskadm.
Question:
Should I remove the hardware raid on c1t2d0 first?
My purpose using veritas volume manager is to ease of increase the disk size when it required. If to use hardware raid, once partition and disk is used on that partition, it will not that easy to expand size. Please correct me if my understand is wrong and do advice me for better approach.

Why dont you using SVM? You can expand the FS with growfs. VXvm is the powerfull VM, but in case of local rootdisk, easy to use SVM. The best solution for Solaris root disk is SVM, except ZFS. IMHO

Hi All,
Thanks for all your reply. I decided to use back the hardware RAID without using software RAID.
At this moment, I'm just use ufs instead of SVM or ZFS; need further study on that before able to use.
Also, have no idea about ZFS route.
Dear All ,
we have hardware raid 1 implemented on Solaris Disks.
We need to patch the Servers. Kindly let me know how to patch hardware raid implemented Servers.
Thanks...

The documentation doesn't make it clear if:

Hi,
I have a root with hardware RAID on c0t0d0 and c0t2d0. I would like to set the boot device sequence in OBP for both hdds.
I have checked in ls -l /dev/rdsk/ for the path of c0t2d0 but it does not exist. Can anyone shed some lights on this?
