Solaris : Corrupt label; wrong magic number errors

Is this a replacement non SUN labeled drive or one that went bad??

The situation will dictate.
I.e. use format and partition to print the partition table

Is your ZFS pool mirrored?

zpool status

@un1x86 , yes the ZFS Pool is mirrored but the 2 disks with corrupt label don't appear in the zpool status, i am not sure if there are data in these disk, don't really know how to check.

@Arnold , no its not a replacement drive. It seems that the drive went bad.

If there are data on these disks, do you think relabel the disk can erase data???

bash-3.00# zpool status -v rpool

You enable/query smart status on the drive.
Do not specify the slice
prtvtoc /dev/dsk/c1t6d0

Do not label or try until you confirm that it is not used anywhere. At this point it is not reflected as mounted.
You may want to explore whether you want to clone it using dd though it is a 146GB in size.

@arnold , how do I enable/query smart status on the drive. Do I only need to type prtvtoc /dev/dsk/c1t6d0 or there are additional commands to enable the smart status.

How can I confirm that the disk is not used... I am not familiar with zfs

zpool status -v tank
