Dear Hicks/Germany ,

Pl see the below output ,

Code:
 metadb
        flags           first blk       block count
     a m  pc luo        16              8192            /dev/dsk/c1t3d0s7
     a    pc luo        8208            8192            /dev/dsk/c1t3d0s7
root@  #
root@ # metastat
d10: Concat/Stripe
    Size: 1170211752 blocks (558 GB)
    Stripe 0:
        Device     Start Block  Dbase   Reloc
        c1t3d0s0          0     No      Yes

Device Relocation Information:
Device   Reloc  Device ID
c1t3d0   Yes    id1,sd@n5000cca025002fa8
root@ #
root@  # swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c1t0d0s1   32,1      16 32768720 32768720
root@  #
root@ # zpool status
no pools available
root@  #

From the above output , the third disk c1t3d0 is used for SVM.

and also the swap is used by c1t0d0.....

So Kindly describe how to do the patching in case if we have hardware raid and also SVM in same server.Or any other ways to handle this.As there is no backup available for the above servers, I am going to split the hardware raid and do the patching. So how to take care of this third disk under SVM.

Rgds ,

Yes, c1t3d0 slice 0 is used by SVM for d10, but d10 is not used anywhere, so you don't need to do any extra steps for SVM.
I have no experience with this HW RAID; I would do
Code:
raidctl -l c1t3d0

to see if it maps to the Disk: 0.3.0

so you're playing Russian roulette, eh?

I really hope that it's not a production server!!!!

Dear Hicks/Germany ,

There is one mount point for the d10 in SVM , it is as below.

/dev/md/dsk/d10 /dev/md/rdsk/d10 /infovista_coll , so do we have to take backups of this /infovista_coll and also , do we have to take any precautions in d10 or do we have to unmount for patching OR simple do the patching....

Pl let me know;
