I am using Sun Netra 440 and i see below error.

When i run metastat, i see 1 disk is in Need Maintenance state.

After that i run below command and getting I/O error

Please help me on this.

Hi Sid, as the 'Invoke' states, you need to specify a new device (disk) to replace the failed one. Do you have a replacement you could swap it out with? If so, this would be assigned a new device name and you can use that to invoke metareplace. You might need to format it to match the original first though.

Am I to assume you replaced the drive? Or were you just trying to run metareplace -e d50 c1t0d0s0 without having replaced the drive? The errors are showing the drive as unavailable so looks to be bad drive


What does format show for c1t0d0s0?

also provide dumpadm output, metadb -i,metastat -p


Is this the OS drive? c1t0d0s0 usually is.


metareplace -e d50 (device) is correct when replacing with itself. you can try to use the same drive without replaceing(usually fails) or after disk replacement.

I have not replaced the drive, i just run the metareplace command.

Below is the output of all the command. It looks like the disk has gone bad and i need to replace the DISK.

How I can identify which one is OS DISK?

bash-2.03# format

So your drive 0 and 1 are mirrored together from what I see. Most likely you boot drive was c1t0d0(dead at this point) but since it is mirrored it really up and running off c1t1d0 at this point.
Your dump device is pointing to c1t0d0s1 which needs to be changed run dumpadm -d /dev/md/dsk/d60 which is the mirror (should not point to individual drive. You also have to change this do to the fact you are about to replace drive c1t0d0.

Then run dumpadm again to confirm the change.

Then delete the metastat database replicas on c1t0d0s3 and c1t0d0s4. run metadb -d c1t0d0s3 c1t0d0s4. Then run metadb -i to confirm they are gone.

look at this link to remove bad drive(turns on blue led for drive identification purposes, then install the replacement and run commands for the os to recognize it.

http://slashzeroconf.wordpress.com/...isk-non-hardware-raid-sun-firetm-v440-server/

Then follow this link to complete the metastat portion which includes the repartition of the replacement drive to match c1t1d0 partition table(this has you copy the partition table from the remaining good drive to the recently replaced drive. Then reinstall the bootblock to the new drive, rebuild your state database replicas, and run metareplace -e d50 c1t0d0s0, then metareplace -e d60 c1t0d0s1 and so on until you ran that command for each portion of the mirror...see link
