Reporter. The following example reports disks whose total I/O is 150/sec or more.

PD Example 4
Component --Identifier-- -------Description----------
PD 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, and
showfirmwaredb.

PD Example 5
Component --Identifier-- -------Description----------
PD -- 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.
