Here is the correct process for ensuring discovery of drives in an array (MSA, say) connected to a (DL360, for example) server.
- Ensure Hot Swap is disabled
- Power up the server
- Launch the Array software
- Go to Advanced and ensure Enable Hot Swap is disabled
- Save as Default
- Close the Array software
- Shut down the server
- Power up the array - wait until all drives have stopped blinking - once up and running, wait a further two/three minutes
- Launch the Array software
- Should see all present drives
- If not: close software and re-try.
