B. Solaris Volume Manager Quick Reference
The following procedure describes how to increase the performance of the ufsdump command when you use it to backup a mounted filesystem located on a RAID-1 volume.
You can use the ufsdump command to backup the files of a mounted filesystem residing on a RAID-1 volume. Set the read policy on the volume to "first" when the backup utility is ufsdump. This improves the rate at which the backup is performed.
# metastat d40 d40: Mirror Submirror 0: d41 State: Okay Submirror 1: d42 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Size: 20484288 blocks (9.8 GB)
A mirror that is in the “Maintenance” state should be repaired first.
