this confims that the disk is faulty. metastatshows:
The "last Erred" means the d10 mirror is already degraded, and can have all types of data corruption.
I have no experience how to go from there. Hope you have a good data backup.

Yes, I still have a bad disk, but at the moment I dont have a new disk. I am stuck on the line that says that I have to remove any metadb on the failed disk!
How to identify the metadb on the failed disk. the failed disk is c0t0d0but the metadb command shows the following:

Your c0t0d0 is not part of the SVM setup so therefore you don't need to remove it from SVM. But it may be part of dump device or swap, do dumpadm or swap -l

Hi Gurus, I've got an issue here:

Hi all,
we have an existing system that was configured using just one of the (two) internal disks. I want to mirror the disk using SVM, but have realised there is no free slice for creating the metadb's. Is there a workaround I can use for this?
In the past we have always kept slice 7 free -... (8 Replies)
