Hi All,

Thanks for all your input you guys are amazing! I used Soltice Disksuite
4.2.1 (free download from SUN)
The client wanted to go with a RAID5 config.

So.....I installed Soltice Disksuite 4.2.1 and implemented a Raid5 config (I
think :-\ )
I used 3 slices from 3 different disks with each slice at 4gb.
With SDS I made these slices replicas then moved them onto raid.

then
ran metastat d0
d0: RAID
            State: Okay
            Interlace: 32 blocks
            Size: 25157368 blocks
Original device:
            Size: 25161024
                        Device Start Block Dbase
State Hot Spare
                        c0t9d0s0 5042 Yes
Okay
                        c0t8d0s3 5042 Yes
Okay
                        c0t12d0s0 5042 Yes
Okay
                        c0t12d0s1 5042 Yes
Okay

Is this all I do?????????
Please let me know what I am missing.
How does the data become redundant? Does all data written become redundant
automagically or do I specify which filesystems?

Also, every time I reboot I get the following errors/warnings:

/dev/rdsk/c0t9d0s7: I/O error
Can't open /dev/rdsk/c0t9d0s7
/dev/rdsk/c0t9d0s7: CAN'T CHECK FILE SYSTEM.
/dev/rdsk/c0t9d0s7: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
/dev/rdsk/c0t8d0s4: I/O error

/dev/rdsk/c0t8d0s4: CAN'T CHECK FILE SYSTEM.

WARNING - Unable to repair one or more of the following filesystem(s):

            /dev/rdsk/c0t8d0s1 /dev/rdsk/c0t8d0s3 /dev/rdsk/c0t8d0s4
/dev/rdsk/c0t10d0
Run fsck manually (fsck filesystem.).

Type control-d to proceed with normal startup...

Is there a fix for this mess?

TIA,

MF
