CMMVC6421E: The specified size exceeds the maximum permitted for this feature.

Explanation

  • A chiogrp command was attempted where the maximum bitmap memory for one or more functions was exceeded. The maximum supported amount of bitmap memory for the RAID function, the Volume Mirroring function and the Metro Mirror or Global Mirror Copy Services functions is 512 MB. The maximum supported amount of bitmap memory for the FlashCopy® function is 2048 MB.
  • Alternatively, a remote copy was attempted that used a memory size of 512 MB when the value of the remote_copy_free_memory variable reached 0. This scenario is unlikely.

User Response

Retry the command, specifying a smaller amount of memory where necessary.
