LD ld:R1.usr.0 LD has reduced availability. Current: ch, Configured: cage
LD Suggested Action 3
LDs are created with certain high-availability characteristics, such as ha-cage. If chunklets in an
LD get moved to locations where the Current Availability (CAvail) is not at least as good as the
desired level of Availability (Avail), this condition will be reported. Chunklets may have been
manually moved with movech or by specifying it during a tune operation or during failure conditions
such as node, path, or cage failures. The HA levels from highest to lowest are port, cage, mag,
and ch (disk).
Examine the identified LD(s) using CLI commands such as showld, showld –d, showldch, and
showpd for any failed or missing disks. In the example below, the LD should have cage-level
availability but it currently has chunklet (disk) level availability (i.e., the chunklets are on the same
disk).

LD Example 4
Component -Identifier-- -----Description-------------
LD -- Preserved data storage space does not equal total node's Data
memory
LD Suggested Action 4
Preserved data LDs (pdsld's) are created during system initialization (OOTB) and after some
hardware upgrades (via admithw). The total size of the pdsld's should match the total size of all
data-cache in the storage system (see below). This message will appear 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.
