Syntax: 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: modify ch="new chassis name" where 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: add spares allunassigned [forced] remove spares all where 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 HP Array Configuration Utility 65
