controller nodes, use the CLI showport command to determine if a port is offline or misconfigured. A
missing or rebooting controller node will cause a port to be offline.

ld
• Checks preserved LDs.
• Verifies that the current and created availability is the same.
• Verifies the owner and backup.
• Verifies the preserved data space (pdsld) is the same as the total data cache.
• Verifies the size and number of logging LDs.
• Displays LDs that are in a failed or a degraded state.
• Displays LDs that are mapped to volumes.
• Displays LDs that are in write-through mode.

Component -------Summary Description-------- Qty
LD LDs not mapped to a volume
Component -Identifier-- --------Detailed Description---------
LD ld:vv.9.usr.3
ld suggested action 1
Examine the identified LDs using CLI commands such as showld, showld –d , showldmap,
showvvmap, and other such commands.
LDs are mapped to VVs. However, an LD can become disassociated from a VV for two reasons: 1) if the
VV is deleted without the underlying LDs being deleted too, and 2) if you use the aborted tune operation.
Most often you remove the unmapped LD to return its chunklets to the free pool.
