If there are multiple drive types when selecting all The drivetype parameter specifies the drive The arrayaccelerator parameter specifies the arrayĪccelerator state for the logical drive. The sectors parameter specifies the sectors per track of the The stripesize parameter sets the logical drive’s stripesize. If not specified, the default is the maximum possible The size parameter specifies the size of the logical drive, the For example, RAID 1 will only be available if twoĭrives are selected while RAID 1+0 will be shown for a selection of 4 or Of certain raid settings depends on the number of drives designated in the Specified, the default raid is the highest level possible. The raid parameter sets the raid level of the logical drive.

The allĪnd allunassigned keywords both target all physical drives that are not SomeĬontrollers may also support port:box:bay and use the #:#:# syntax. #:# stands for port:id or box:bay, depending on the controller. If the drives specified are all assigned to an existingĪrray, then a new logical drive will be created on that array. If the drives specifiedĪre all unassigned drives, then a new array will be created with a new The drives parameter specifies the physical drives to be used forĬreating a logical drive on a new or existing array. The type parameter specifies the device type that is being created.Ī logical drive is the only device type supported at this time. Sets the array accelerator cache ratio for the controller. Target can be any valid logical drive target on a controller that supports modify Įnables or disables the array accelerator for a given logical drive. The following documentation pertains to your search: When you are stuck for a particular command, you can just run “help ” for more input. In case it wasn’t set to an optimal value it can be changed using the command “ ctrl slot=5 modify cacheratio=0/100” In this case it has been set to an optimal value.

In the above output our point of interest was “ Accelerator Ratio: 0% Read / 100% Write“. Logical Drive Label: A0432BCEP61630K9SW31NLD55F Parity Initialization Status: Initialization Completed “ctrl all show config detail” Will give you the entire controller configuration. Navigating using hpacucli is very straight forward. The command line utility to check the controller configuration is “hpacucli”. The machine configuration is HP DL180 G5, 2 x Xeon L5420 2.50GHz, 15.7GB / 16GB 667MHz DDR2, 6 x 300GB-15K SAS.This machine was running mysql 5.1.36 using the innodb plugin. Our ideal preference was a read/write ratio of 0/100. I was given the task of checking the array accelerator cache ratio and see if it was set to optimal levels.
