ld
suggested action 2
Examine the identified LDs using CLI commands such as
showld
,
showld –d
,
showldch
, and
showpd
for any failed or missing drives. Write-through mode (WThru) indicates that host I/O operations
must be written through to the drive before the host I/O command is acknowledged. This is due to a node-
down condition, when controller node batteries are not working, or where drive redundancy is not optimal.

LD LDs with reduced availability 1
Component --Identifier-- ------------Detailed Description---------------
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 wanted level
of availability (
Avail
), this condition is reported. Chunklets might have been manually moved with
movech
or by specifying it during a tune operation or during failure conditions such as controller node,
path, or cage failures. The HA levels from highest to lowest are
port
,
cage
,
mag
, and
ch
(
disk
).
Examine the identified LDs using CLI commands such as
showld
,
showld –d
,
showldch
, and
showpd
for any failed or missing drives. In the following example, the LD must have cage-level
availability, but it currently has chunklet (drive) level availability (the chunklets are on the same drive).
