Boot System from alternate mirror disk

Hi All,

I have one x6270 m2 Server running solaris 10 on 2 internal disks one is root disk & another is mirror disk. Due to some firewall issues I am not able to open the remote console. But I can ssh on the ILOM IP from terminals. Now the problem is I want to boot my system from alternate disk. Do anyone the way to boot the system from alternate disk. Further after booted up I want to check the currently using disk also.

Thanks in advance!!

    Hi,

    Yes, you can specifically boot from the alternate disk.

    I have an x4270m2 so I'm not sure what kind of disks you have.
    You'll have to consider the device differences.

    Here's my mirrored root pool:

    # zpool status
    pool: rpool
    state: ONLINE
    scan: resilvered 71.8G in 0h8m with 0 errors on Wed Dec 5 08:00:51 2012
    config:

    NAME STATE READ WRITE CKSUM
    rpool ONLINE 0 0 0
    mirror-0 ONLINE 0 0 0
    c0t5000CCA012C8323Cd0 ONLINE 0 0 0
    c0t5000C500438124F3d0 ONLINE 0 0 0

    errors: No known data errors

    I would need to boot this system specifically from the second disk,
    c0t5000C500438124F3d0, from the system's BIOS.

    Then, you can identify from which disk the system is currently booted,
    like this:

    # prtconf -v|sed -n '/bootpath/,/value/p'

    Thanks, Cindy

    you should see the primary disk set in the output.

    set the parameter for the secondary/mirror disk, give it a name.

    boot the system to ok> prom.

    from ok> boot <your secondary/mirror disk name>
