Isilon: After migrating to L3 cache, all SSDs are in REPLACE status

All the SSDs are in [REPLACE] mode after switching to L3 cache.

While the drives are migrating to L3 cache, the status of the drives is supposed to change to [L3]. In this case, the drive migration was not successful, so all the SSDs are in [REPLACE] status.

1) SSH to the node that is experiencing the problem.

2) Verify the bays and drives that are experiencing the issue by running the isi devices command. Note: This method shows SSDs.

Here is an example of what is seen:

isilon# isi devices
Node 1, [ OK ], [SED Node]
Bay 1        Lnum 11      [REPLACE]      SN:********            /dev/da1
Bay 2        Lnum 12      [REPLACE]      SN:********            /dev/da2

3) Use the format command to format the drives in [REPLACE] state.
 

isi devices -a format -d <Node Number>:<Bay Number>

For this example, run these commands.
 

isi devices -a format -d 1:1
isi devices -a format -d 1:2

4) Once the format is complete, run the isi devices command to verify that the format was successful. If the format was successful, the drive status shows [PREPARING] state.
 

isilon# isi devices
Node 1, [ OK ], [SED Node]
Bay 1        Lnum 11      [PREPARING]      SN:********            /dev/da1
Bay 2        Lnum 12      [PREPARING]      SN:********            /dev/da2

5) Wait for 20-30 minutes for the format process to complete. Once it finishes, your isi devices output should look like this.
 

isilon# isi devices
Node 1, [ OK ], [SED Node]
Bay 1        Lnum 11      [L3]      SN:********            /dev/da1
Bay 2        Lnum 12      [L3]      SN:********            /dev/da2
