Viewing SSD physical drives
The ssdphysicaldrive keyword is a valid target for the show command, and it outputs the solid state
physical drives on the specified controller.
Syntax:
<target> ssdpd all show [detail]
where the target is any valid controller.
Example commands:
controller slot=5 ssdpd all show
controller slot=5 ssdpd all show detail
Viewing SSD information
The ssdinfo keyword provides a summary for solid state drives for the specified controller.
Syntax:
<target> show ssdinfo [detail | summary]
Command examples:
controller slot=1 show ssdinfo
controller all show ssdinfo
controller all show ssdinfo detail
controller all show ssdinfo summary
Assigning a chassis name to the controller
If a controller is configured with at least one logical drive, you can give the controller a simplified name (the
chassis name) to make it easier to identify and enter the correct controller in a command.
Syntax:
<target> modify ch="new chassis name"
where <target> is a controller. If you change the chassis name of a controller that you have set as the
default target
("Setting the
Example commands:
=> ctrl sn=P56350D9IP903J modify ch="Lab 6"
=> ctrl ch="Lab 4" modify ch="Lab 6"
Managing spare drives
Assigning one or more online spare drives to an array enables you to postpone replacement of faulty drives.
However, it does not increase the fault-tolerance level of any logical drives in the array. For example, a
logical drive in a RAID 5 configuration suffers irretrievable data loss if two of its physical drives are
simultaneously in a failed state, regardless of the number of spare drives assigned to the array.
Any drive that you want to use as a spare must meet the following criteria:
•
It must be an unassigned drive or a spare for another array.
•
It must be of the same type as existing drives in the array (for example, SATA or SAS).
•
It must have a capacity no less than that of the smallest drive in the array.
Syntax:
<target> add spares=[#:]#:#,[#:]#:#,[#:]#:#–[#:]#:#,...|allunassigned

target" on page 60), you must reset the target.
