Dear Sun gurus,
I have Sun Fire[TM] V240 server with its StorEdge 3300 disk-array. Following are its disks appeared in format command. I have prepared its partitions thru format and metainit & metattach (may be i have made wrong steps, causing the errors below because I have done thru some document given by my fellow and formed d26 mirror with submirrors as d27=disk2 & d28=disk3).
AVAILABLE DISK SELECTIONS:

But after rebooting, it gives me following errors repeatedly and my filesystem is hanged after sometime.

After rebooting again, this file system works normally, but after 1 or 2 days, it takes very long time (20~30 seconds) to write/read and execute commands (even ls takes longer time) and eventually, it gets hang. When I run "metastat" after rebooting the machine, it shows my disk state as below.
d26: Mirror
Submirror 0: d27
State: Needs maintenance
Submirror 1: d28
State: Needs maintenance
Pass: 1

Write option: parallel (default)

Kindly suggest me in detail so that I can remove the partitions and retry to format. I need your help as I am not good in Sun and its utilities.
Thanks.
