Hello,
The problem has been just resolved, but not as what we expected the way the problem should be resolved.
What we did was that we have found a similar structure server as spare, so our original idea was to shut down this spare server, boot to BIOS, check it's disk mirroring setting, pull one disk out, boot up to see the error message, then which might help us to determine which disk was the real bad one.
While local HW team told me they only saw 2 disks in X4100, I started to suspect there was no HW mirroring set-up, so we ran format->analyze->read on spare server, I intentionally picked c2t3d0 ( the one was bad on prod server ), after HW team confirmed they saw the blinking light while doing analyze, we decided to replace the disk on the problem server in the same slot.
After disk was hot-swap, "format", "prtvtoc /dev/rdsk/c2t3d0s2", "raidctl -l" all worked, then my suspicion raised : why I was seeing 2 disks in format? If it's HW mirroring, I should only see 1 disk in "format" ( since it's virtual to OS ).
Conclusion: the X4100 has 2 disks only and never been configured with HW mirroring.

vxunreloc
vxunreloc(1M) vxunreloc(1M)
NAME
vxunreloc - move a hot-relocated subdisk back to its original disk
SYNOPSIS
/etc/vx/bin/vxunreloc [-f] [-g diskgroup] [-n dm_name] [-t tasktag] dm_name
DESCRIPTION
The Veritas Volume Manager (VxVM) hot-relocation feature can detect an I/O failure in a subdisk, relocate the subdisk, and recover the plex
associated with the subdisk. vxunreloc lets you reverse the process and move the hot-relocated subdisks back onto a disk that was replaced
after a disk failure.
dm_name specifies the disk where the hot-relocated subdisks originally resided. The -n option moves the subdisks to a different disk from
where VxVM originally relocated them. For example, when disk03 fails, all the subdisks residing on it are hot-relocated to other disks.
After the disk is repaired, it is added back to the disk group using a different name, for example, disk05. If you wanted to move all the
hot-relocated subdisks back to the repaired disk, you would enter:
/etc/vx/bin/vxunreloc -n disk05 disk03
When vxunreloc moves the hot-relocated subdisks, it moves them to their original offsets. However, if there was a subdisk that occupied
part or all of the area on the destination disk, vxunreloc prints an error message and exits. In this situation, you can use the -f option
to unrelocate the subdisks to a specified disk, but not to their original offsets.
OPTIONS
-f Unrelocates a subdisk to a different offset if unrelocating to the original offset is not possible.
-g diskgroup
Unrelocates a subdisk from the specified disk group. If this option is not specified, the default disk group is determined using
the rules given in the vxdg(1M) manual page.
-n dm_name
Specifies a new disk name to relocate to a disk with a different name.
-t tasktag
Specifies a tag to pass to the underlying utility.
SUBDISK RECORD FIELDS
orig_dmname
When a subdisk is hot-relocated, its original disk media name is stored in the orig_dmname field. When you run the vxunreloc
command to move the subdisk back to the original disk (or to a new disk), this field is cleared. Before you run the vxunreloc
command, you can do a search on this field to determine the subdisks that originated from a failed disk. For example, the fol-
lowing command lists all the subdisks that were hot-relocated from mydg01 in the disk group mydg. Note that you must prefix the
field name with "sd_" for the command to work.
vxprint -g mydg -se 'sd_orig_dmname="mydg01"'
orig_dmoffset
When a subdisk is hot-relocated, its offset into the original disk is stored in the orig_dmoffset field. When you run vxunreloc
to move the subdisk to the original disk, or to a new disk, this field is zeroed. The following command lists a hot-relocated
subdisk which originally resided at disk10 at offset 1000. Again note that you must prefix the field names with "sd_" for the
command to work.
vxprint -g dg01 -se 'sd_orig_dmname="disk10"
&& sd_orig_dmoffset=1000'
EXIT CODES
If the operation fails, vxunreloc exits with a non-zero status. A non-zero exit code is not a complete indicator of the problems encoun-
tered, but rather denotes the first condition that prevented further execution of the utility.
See vxintro(1M) for a list of standard exit codes.
