If you are looking for Procedure for replacement of DAE (Disk Array Enclosure). You can obtain the same from CLARiiON Procedure Generator by following below path in powerlink.emc.com
Home > Support > Product and Diagnostic Tools > CLARiiON Tools > CLARiiON Procedure Generator.
However, it is recommended to get SP Collects Analyzed and if repalcement of DAE is required then to be done by EMC CE.
Removing a DAE which has the vault drives in it, and if this array is in production then the recomnedation in this scenario is to open a case with the Support and ask the CE to be onsite for this activity.
sorry , I didn't mention that my intention is to replace the DAE chassis but not include the disks.
And I looked up the CPG for offline replace CX700 DAE,there is no specific indication for replace DAE chassis within vault
there is no specific indication for replace DAE chassis within vault
There's is none except as you will be replacing Base DAE, this will be an offline activity.
Once the array is powered down.
You'll need to remove the DAE Chasis and replace it with the new one and insert the drive(s) in respective slots.
However, as I and several memeber suggested. This activity needs to be performed by EMC Certified CE.
Request you to Open Server Request with EMC Technical Support with regards to same.
