disk:3

Detailed State: old_firmware

PD Suggested Action 4

The identified disk does not have firmware that the storage system considers current. When a disk

is replaced, the

servicemag

operation should upgrade the disk's firmware. When disks are

installed or added to a system, the

admithw

command can perform the firmware upgrade. Check

the state of the disk using CLI commands such as

showpd -s

showpd -i

Component --Identifier-- -------Description----------

Sparing Algorithm is not set

PD Suggested Action 5

Check the system’s Sparing Algorithm value using the CLI command

showsys -param

. The value

is normally set during the initial installation (OOTB). If it must be set later, use the command

setsys

SparingAlgorithm

; valid values are Default, Minimal, Maximal, and Custom. After setting the

parameter, use the

admithw

command to programmatically create and distribute the spare

chunklets.
