HP Array Configuration Utility 65
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 target" on page 58), you must reset the target.
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
[forced]
<target> remove spares=[#:]#:#,[#:]#:#,[#:]#:#–[#:]#:#,...|all
where <target> is an array (or logical drive, if the array contains only one logical drive). The forced
parameter represses any warning message prompts. If you specify a drive range, any drives in the range that
do not meet the previous criteria are not used.
Example commands:
=> ctrl slot=3 array B add spares=1:6
=> ctrl slot=4 array all add spares=1:5,1:7
=> ctrl slot=5 array A add spares=1:1–1:5
=> ctrl slot=5 array A remove spares=1:1–1:5
