UNIX Solaris
1

Hi All, I'm new to this site. I have a few question since I'm in the process how to to repair my raid on Sun V240 Server.

  1. How can we create RAID in Sun Sparc v240?

  2. What utility can help people create RAID in Sun Sparc v240?

  3. Do we need any special software to create the RAID?

  4. How can we repair RAID volume?

Thx
Angkor

# metastat

Hi, When I typed that command I get this message below. I'm not sure what raid I have currently. Here is my disk info:

dev240-global> metadb
metadb: dev240: there are no existing databases

dev240-global> cat /etc/vfstab

looks like you have NO raid at all...

Hi, is no raid how can I repair my disk if it already corrupted. Is there any utility I can run or command? Thx

10

try fsck ... but if the disk has hardware errors this won't fix the errors!

11

Hi, I tried that it still the same. Is there a utility that can fix the file system if it crash?

12

What is "still the same". You haven't described any symptom yet.

As already stated, fsck. There is even better, a file system that doesn't crash by design and so doesn't need fsck. Unfortunately, you aren't using it (zfs).

hi u dont have metdevices on ur server which seems from ur output..... first u have to create meta database after then u are able to create software raid.....
