An aggregate has experienced a multiple disk failure due to a failing I/O module (IOM). The module has been replaced and the aggregate is still failed. What step can be taken to recover the aggregate?
Suggested Answer: C Vote an answer
When an aggregate fails due to multiple disk failures caused by a faulty I/O module (IOM), the first step after replacing the faulty IOM is to manually unfail the affected drives. This process is done in maintenance mode.
Steps to Recover the Aggregate:
Enter Maintenance Mode:
Reboot the node and interrupt the boot process to access maintenance mode.
Identify Failed Drives:
Use the command:
sql
Copy code
storage show disk -broken
This command lists all failed (broken) drives.
Unfail the Drives:
Use the following command for each failed drive:
php
Copy code
disk unfail <disk-name>
Reconstruct the Aggregate:
Once all drives are unfail, the system should begin reconstructing the RAID groups in the aggregate.
