Hi Managers,
I have a SUN SE 3510 FC Array with dual RAID controllers
connected to two V880 servers with identical configuration
to build a HA solution with Sun Cluster 3.0 5/02:
SunOS server1 5.9 Generic_112233-08 sun4u sparc SUNW,Sun-Fire-880
SunOS server2 5.9 Generic_112233-08 sun4u sparc SUNW,Sun-Fire-880
The firmware vesion of the Array is 3.27K.
Two RAID 5 sets are created with 1.33TB and 1.47TB in size
on the Array.
The servers can see the drives no problem, but there is
no backup slice (slice 2) created by default, see prtvtoc
output for the RAID set with 1.33TB below:
========= begin prtvtoc =========
* /dev/rdsk/c3t44d0s2 partition map
*
* Dimensions:
* 512 bytes/sector
* 2862141440 sectors
* 2862141373 accessible sectors
*
* Flags:
* 1: unmountable
* 10: read-only
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 2 00 34 262144 262177
1 3 01 262178 262144 524321
6 4 00 524322 2861600700 2862125021
8 11 00 2862125022 16384 2862141405
========== end prtvtoc ========
The real problem is Sun Cluster insist to use slice 2 to
add a quorum device, following is the error when adding
a quorum device with above RAID set:
========== error begin ========
Which global device do you want to use (d<N>)? d17
Is it okay to proceed with the update (yes/no) [yes]?
scconf -a -q globaldev=d17
Sep 26 14:14:34 server1 cl_runtime: WARNING: CMM: Open failed with error
'(No such device or address)' and errno = 6 for quorum device
'/dev/did/rdsk/d17s2'
scconf: Failed to add quorum device (d17) - unable to scrub the device.
Sep 26 14:14:34 server1 . Unable to scrub device.
Command failed.
=========== error end ========
I tried to rebuild partition table and create a backup slice
manually, but Sun Cluster does not recognize it. In fact even
format does not recognize it, it is considered a regular
slice ocuppying the whole disk, although I set the Tag(5)
and Flag (01) right for a backup slice.
Can anybody help me out on this? I'll summarize.
Thanks,
Qing Chang
