The problem described in this article can have multiple symptoms and errors. One of these issues described in this article can occur right after disk replacement, or when disk was not correctly replaced in the past. When this problem happens there will be a mismatch of Solaris Volume Manager (SVM) disk Device ID (DevID) is in the metadb that causes various errors and meta command failures.
In below example, the DevID in metastat output for disk c1t1d0 does not match the DevID in /etc/lvm/mddb.cf and /kernel/drv/md.conf despite metadevadm -u command was done. Beware that depending on your server the name of the disk can also be a WWN disk name like "c0t5000C5004382FDCFd0s0".
You will need to enter maintenance mode and delete the metadbs on the disk that got the metadevadm error.
The following document has the metadb commands to run.
