Solaris

Hi everyone

I have a problem. My configuration is as follows:

Sun 280R server
2 x internal disks
3 x state databases on disk 1
3 x state databases on disk 2

Disk 1 was giving errors, so I cleared the mirrors on it, deleted the state databases and replaced the disk. Before attaching the sub-mirrors and re-creating the state databases I rebooted the server and now it's unable to boot. With hindsight it was probably a stupid thing to do, but now I've got to fix it.

Please see the screenshot below:



Booting from a CD is no use, because I cannot access state databases with the metadb command.

Can anyone perhaps help me solve this problem?

If I understand correctly, you have one good disk with file systems, and one new disk with nothing on it yet. You will need to boot from cdrom (or the net) and do some clean up.

Step 1 - boot from cdrom; mount the root file systems on the good disk; comment out the root md entry in /etc/system and change the md file system entries in /etc/vfstab to be ctd entries
Step 2 - boot from the good disk and recreate the md database and recreate the metadevices

good luck

Thank you erice, you are a life saver.

Doh!!!

I've followed the advice above, but when I boot from the good disk and run metadb, it returns the following error message:

there are no existing databases

I don't know how this is possible, but what can I do now?

Please re-create the metadb and mirrors again. That's Step 2

1. Delete the metadb which you have created.
2. Create the 7th partition again of 512 mb
3. create the metadb
metadb -a -f -c 3 c0t0d0s7

# metainit -f d11 1 1 c0t0d0s0
d11: Concat/Stripe is setup
# metainit d12 1 1 c0t1d0s0
d12: Concat/Stripe is setup
# metainit d10 -m d11
d10: Mirror is setup
# metaroot d10
# lockfs -fa
# reboot
...
# metattach d10 d12
d10: Submirror d12 is attached

1. Boot the system in single user mode.
2. mount the root partition on mnt
3. change the /etc/vfstab file to normal file system path
change /dev/dsk/c0t0d0s0 /
reboot the system
You will be able to reboot the system at previous stage without SVM.

After successfully booted system you can recreate SVM by previous posted step
