LD LDs with reduced availability 1
Component --Identifier-- ------------Description---------------
LD ld:R1.usr.0 LD has reduced availability. Current: ch, Configured: cage
11.4.4.7 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).
