I have two Sun x4200 servers, and I've noticed the internal disk drives have different cylinders; therefore, it prevents me from mirroring the drives with ZFS software raid. After several suggestions from Sun; they still can’t provide the solution.They also shipped us a new drive; but still seeing different cylinders.
the Primary drive (c0t0d0) has a 14086 cyl( with OS installed). while the secondary drive (c0t1d0) has 8921 cyl. (blank disk).
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <DEFAULT cyl 14086 alt 2 hd 24 sec 424>
1. c0t1d0 <DEFAULT cyl 8921 alt 2 hd 255 sec 63>
Specify disk (enter its number): ^D
Both are 73gb with same Sun part number.
Sun has suggested:
1) re-partition the secondary drive with fdisk 100% Solaris.... didn't work
2) shutdown the server and boot cdrom to install os on the secondary drive... didn't work
3)they shipped a new drive to us.....replaced the secondary drive....didn't work.
4)they are requesting me to run format>anaylyze>purge to clean the fdisk partition...still running.
I told them it's rediculous to have to shutdwn the server and install OS just to replace a failed drive.
their respond was that we must try it before they can proceed to other solutions.
Has anyone encouter this issue?
P.S. OS is solaris 10 x86 10/09
