UNIX for Advanced & Expert Users

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:
0. c1t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@1c,600000/scsi@2/sd@0,0

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

WARNING: md: d27: write error on /dev/dsk/c2t8d0s6
WARNING: /pci@1c,600000/scsi@2,1/sd@8,0 (sd22):

-OR-

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

Read option: roundrobin (default)
Write option: parallel (default)

c2t8d0s6 0 No Last Erred

d28: Submirror of d26

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.

Hi,
so far i now this is a hardware failure.

SCSI transport failed: reason 'reset': giving up

You can test the bevavior by changing the disk or/and the diskarray.

Best regards
