I'm using a Sun Solaris 4500 with a StorEdge 5200 box running Solaris 9.
I'm using Sun's logical volume manager to arrange the 22 disks in a 0+1
array for different volumes u01, u02, u03. The disks are arranged as
follows:
/u01
Mirror d1
Submirror d11 (RAID 0)
Submirror d12 (RAID 0)
/u02
Mirror d2
Submirror d21 (RAID 0)
Submirror d22 (RAID 0)
/u03
Mirror d3
Submirror d31 (RAID 0)
Submirror d32 (RAID 0)
I ran metastat and noticed that all volumes have disks that have the State
of "Last Erred" or "Maintenance." The disks themselves are new and I'm not
sure how to clear the errors. Earlier, I ran metadetach on a submirror and
then rebuilt the mirror and the message of "Maintenance" went away but that
seems awfully round-about. What is the easiest, recommended way to clear
these errors. I've included the output for /u02's metastat as a reference.
# metastat d2
