If the active database replicas reduced bellow half the will not come up. In such condition we can boot the system with the physical address of the root disk or the root mirror disk, which one is in good state. boot to single user mode. check the failed database replicas by 'metadb -i' command.

delete the failed replicas using 'metadb -d' command.

Then reboot to normal mode. after that we can replace the failed disk and regenerate the raid using 'metareplace' command.

In solaris RAID half of replicas fails Suppose out of 6 replica 4 got failed -> what will be the impact if system will not come up & if system will not come up how to fix this issue.
