Preserved data storage space does not equal total node's Data
memory
LD Suggested Action 4
Preserved data LDs (pdsld) are created during system initialization (OOTB) and after some hardware
upgrades (via
admithw
). The total size of the pdsld should match the total size of all data-cache
in the storage system (see below). This message appears if a node is offline because the comparison
of LD size to data cache size does not match. This message can be ignored unless all nodes are
online. If all nodes are online and the error condition persists, determine the cause of the failure.
Use the
admithw
command to correct the condition.
