•Safely power down a CLARiiON CX-Series array
1.The only power switches that should be used to shutdown a CLARiiON CX-Series array (SPE/OS-boot chassis or DPE) are the power switches on the standby power supplies (SPS).
2.Perform the applicable procedure:
For CX700/CX600 arrays:
a. Stop all I/O to the array.
b. Wait approximately 5 minutes to allow the write cache to finish its writes to the storage system. Writes may not be completed but following this procedure will ensure data integrity.
c. Turn off the SPS power switch on each SPS.
d. As soon as the second SPS is turned off, any data in the SP (cached data) will be saved to the vault drives.
e. When the saving of the cached data from the SP is completed (up to 90 seconds), the SPS units will power off by themselves, thus removing power to the SPE chassis and the OS-Boot chassis.
f. Once this is complete and the SPS units have turned both themselves and the power supplies connected to them off, any other chassis can be turned off by using the power supply switches or removing cables from their AC source.
For all other CX-Series arrays:
NOTE: A CX200 or CX300 may have only one SPS where the A-side power supply (right rear) is plugged into the SPS and the B-side power supply is connected directly to the AC source.
a. Stop all I/O to the array
b. Wait approximately 5 minutes to allow the write cache to finish its writes to the storage system. Writes may not be completed but following this procedure will ensure data integrity.
c. Turn off the SPS power switch on each SPS.
WARNING: Never turn off the power directly to the SPE chassis by using any switches on the power supplies. Never unplug any of the AC cables going to the SPE chassis to disconnect power.
d. As soon as the last SPS is turned off, any data in the SP (cached data) will be saved to the vault drives.
e. When the saving of the cached data from the SP is completed (up to 90 seconds), the SPS units will power off by themselves, thus removing power to the DPE chassis.
f. If the array is a CX200 or CX300 with one SPS, power off the power supply that connected directly to the AC source, AFTER the power supply that is connected to the SPS has shut down down
