Make an iSCSI LUN clone bootable

UNIX Solaris
1

trying to do this for a DR situation. I've cloned an iSCSI LUN to another server. I've created an LDOM on it. set the LDOM to auto-boot=false and exported the LUN as a raw disk to the new LDOM. After starting the LDOM and telnetting to it. I can get to the OK prompt and see the disk but when I try to boot into single user mode I get the following output.

{0} ok boot disk0

how to do I make it executable?

I need to ask some questions first......

You copied an iSCSI filesystem to another machine and want to make it bootable. This filesystem is not iSCSI connected on the DR system; it is a normal directly connected disk??

This may sound like a stupid question but this filesystem has a Solaris O/S already installed (before you copied it over)?

Do you have the DVD media of this O/S?

Also, what type of filesystem is it? UFS or ZFS?

. boot from iso or boot from net into single user mode of the guest domain 

ex:boot cdrom:f or boot net:dhcp -s 



#2. zpool import & check for rpool is available. 

3. zpool import -R /a rpool. You can ignore the errors it thrown below. 

# zpool import -R /a rpool 
cannot mount �/a/export': failed to create mountpoint 
cannot mount �/a/export/home': failed to create mountpoint 
cannot mount �/a/rpool': failed to create mountpoint 

4. # zfs list 

5. Mount the root dataset 

ex: zfs mount rpool/ROOT/solaris 

6. cd /a ; ls -ltr & see if you can all the files. 

7.Install the boot block: 

#installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/cxdxsx << Kindly replace the cxdxsx with the original boot disk of the guest domain 

8. Update the boot archive 

#bootadm update-archive -fv -R /a
