Solaris

When you are booting the system normally like the below

OK boot

Is going to boot from the primary disk . To boot from the secondary disk we need to specify with the boot some thing like below


OK boot root-mirror

depending on whether you are simply detaching a submirror or tearing down the mirror itself you may need to make some alterations.

if you completely clearing the mirror, you will need to alter your /etc/vfstab to accommodate for the changes made by removing the mirror. where you are mounting your metadevices, you will need to change it to the /dev/dsk/cxtxdxsx and /dev/rdsk/cxtxdxsx nomenclature.

Does that mean there is no way to know which disk the server is using from the OS after it is up?

With the script I am testing, the system will use disk0 to boot from after un-mirroring. When re-mirror, disk1 will sync with disk0. The script is very convenient if you understand how it works. What I am trying to find right now is 1- how to make the server use disk1 instead of disk0 when un-mirror, 2- how to make the server to use disk1 as the primary to sync from after re-mirror.
