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
Component --Identifier-- ------------Detailed Description---------------
LD ld:R1.usr.0
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).
