Finding a Meta Database 
After examining the mirrored disk drives and determining that multiple portions of 
a disk drive are inaccessible, you must remove the hard disk drive. Before you can 
remove the drive, use the metadb utility to determine if the drive in question has a 
metadevice. 
Note:  For more information about metadevice assignments, refer to the 

12-Disk Device Assignments (on page 46) table. 
Complete these steps using the metadb utility to determine if a meta database is 
located on the disk drive. If you have been following the procedures in this chapter 
in order, you should still be logged in to an xterm window as root user.

drive:
