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).
WARNING: Failure to follow this procedure can result in the loss of data and extended times of data unavailability while the array is returned to normal functionality. NOTE: The term “SPE” in this document, generically refers to the chassis that holds the storage processors for several types of arrays. • CX600 - SPE • CX700 - SPE • CX3-20-Series - SPE3 • CX3-40-Series - SPE3 • CX3-80 - SPE2 Perform the applicable procedure: For CX700, CX600, CX3-80, CX3-40-Series, and CX3-20-Series arrays: NOTE: The CX700, CX600, CX3-80, CX3-40-Series, and CX3-20-Series SPE chassis and OS-boot chassis are plugged into the SPS units. From the rear of the cabinet, the left power supply of each chassis (SPE and OS-Boot) is plugged into the left SPS and the right power supplies are plugged into the right SPS. 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 or the OS-Boot chassis by using any switches on the power supplies. Never unplug any of the AC cables going to the SPE or OS-Boot chassis to disconnect power. 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.
