Power Down (Shutdown) & Restart a EMC Clariion Disk Array.

Shut Down Procedure

1. Shut down the hosts

2. Power off the FC switches (Not required unless you want to restart switches too)

3. Turn off the power switches on the Standby Power Supplies (SPS).

This will force the array to flush any data in the write cache out to the vault area on the first five drives. The array will then turn itself off after that has finished - it can take up to 2 minutes.

4. Power off any disk expansion cabinets (DAEs)

Done!

Power On Procedure

1. Power on FC Switches (Takes around 10 minutes to start, so do this first)

2. Power on DAEs

3. Power on SPS

4. Power on Hosts

Done!

Note: There is no way of shutting down or restarting array from Navisphere.
