Quick question, after i had done Raid 1 mirror via SVM. Do i instal bootblk on my root disk or mirror disk ? I remember i done it on root disk but my colleague said it had to be on the mirror disk. Pls kindly advise.
The disk you used to boot from before you created the raid volume already has a boot block. The other one may or may not, depending on the previous usage of the disk.
To be on the safe side, install the boot block on both disks and try to boot from both disks to make sure, everything works as expected.
