Hi, I have mirrored boot disk and I am able to boot from either disk. If I detach mirror would I be able to boot from detached disk? Thanks. Sunil
Did you run installgrub on both disks: /usr/sbin/installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/cxtydzs0 Or the equivalent. If you can''t boot from either, how did either become your boot disk? If you want to use a single mirror member disk to boot from (i.e. for testing), I wouldn''t detach it. Boot from it and let ZFS complain about the missing member of the mirror for the short term. That''s my idea, but I''m not an expert. This process works for me if I''m testing something regarding my mirror or testing a disk or controller. I don''t know how one would boot from a detached disk, but other folks will have more experience. -- This message posted from opensolaris.org
By the way, if you try my idea and both disks remain physically attached, both should be found and the mirror will be "intact", regardless of which disk you boot from. If one is physically disconnected, then you will have complaints about the missing disk, but it should still work if everything is configured correctly and your BIOS doesn''t present you with any difficulties. -- This message posted from opensolaris.org
