Hi all,


I have a V490 running with Solaris 10. The OS disk was mirrored. I wanted to break the mirror, boot with the secondary mirror, and re-mirror the OS with a new disk.

This is what I did,

detached the metadevices of the secondary mirror disk (disk 1)
metaclear-ed the metadevices,
shutdown the machine (basically for some hardware additions)
pulled out the disk 0(main mirror)
booted the m/c with the cd
mounted the s0 slice of disk1 as /mnt
made changes to /etcvfstab (removed the 'md' entries and replced them with the entries of the disk 1 i.e. c#t#d#s# no. of the disk1)
and /etc/system
(deleted the entry pertaining to md)
and finally booted the system with disk1

This is what i got

while the boot-up, after displaying the hostname it gave me an error as
"cron aborted:cannot create fifo queue"
Then there were certain errors saying that / file system is read-only and it does not proceed further,

I dont have the exact error messages.

Please help me out.

Rgds,

Hi,

You can boot with "boot -a" for interactive boot. Press enter to use the defaults (or change if you see a problem) but when you get to the part where you specify your /etc/system file, specify /dev/null to bypass your /etc/system file which maybe you made a mistake editing. The system will boot with a "missing" /etc/system file, but a messed up one could cause problems.

That's how I remember it anyway.

Otherwise if the primary disk is not broken, put it back and boot off it. Re-mirror and then detach the primary, metaclear and boot off secondary.

Hope you succeed.
