Re: purpose of below 4 disks

---------- LOGICAL DRIVE 5 ----------

Raid Level                                         : RAID 1
Volume sas address                                 : 0x85542fd17e4323d
Device Special File : /dev/rdsk/c2t2d0
[...]
0x5000c5000732999d 1 7 140014 PRIMARY ONLINE 0x5000c50007334dad 1 8 140014 SECONDARY ONLINE

 

These two disks are two RAID 1 halves of device /dev/(r)dsk/c2t2d0, also known as /dev/(r)disk/disk5. The presence of _p1, _p2. _p3 suffixes in the ioscan listing (...s1, ...s2, ..s3 in legacy-form ioscan) indicates this is very likely your hardware-mirrored system disk.

 

NOTE: the ioscan also lists /dev/(r)disk/disk3 and /dev/(r)disk/disk4_p1 as belonging to this hardware device. This is not normal. You may have some stale device nodes in /dev/disk and /dev/rdisk directories. "rmsf -x" and/or "insf -eCdisk" could be used to get rid of them. (Warning: if you have custom permissions on your disk devices, "insf -eCdisk" will reset them to factory defaults.)

 

 

---------- LOGICAL DRIVE 7 ----------

Raid Level                                         : RAID 1
Volume sas address                                 : 0xb77fb08daff4530
Device Special File                                : /dev/rdsk/c2t3d0
[...] 0x5000cca0155d48f9 1 6 140014 SECONDARY ONLINE 0x5000c500073299bd 1 5 140014 PRIMARY ONLINE

 

These disks are two RAID 1 halves of device /dev/(r)dsk/c2t3d0, also known as /dev/(r)disk/disk9. According to information you posted, it is not part of the system volume group vg00.

 

It might be:

  • part of some other volume group
  • used as a raw data volume (no LVM used), maybe for a database?
  • completely unused.

 

There was not enough information to determine anything further on these disks.

Thanks a lot MK.
