•
Pending Update Data Rate: Maximum cache % available for use by Continuous Access XP Async
sidefiles.
•

consistency group is not in use, this column is blank.
•
I/O Delay Start (Use firmware version 21.07.04 or later only): Threshold for starting the response
delay to the host.

• Other S/N: Exist: Indicates that there is an RCU other than the one with the lowest serial number.
When there is no other RCU, the column is blank.
