Deleting CacheCade Virtual DisksTo delete CacheCade virtual disks, perform the following steps in the BIOS Configuration Utility:1. Press to access the Virtual Disk Management screen.2. Use the arrow keys to move the cursor to the CacheCade Disk Group or Virtual Disks heading.3. Press .The Action menu is displayed.4. Select Delete VD and press .NOTE: Warning messages are displayed stating the effect of deleting a virtual disk. Click OK to complete thevirtual disk deletion.NOTE: In operating system management applications, a CacheCade virtual disk deletion or removal can bedone without interrupting any I/Os. The controller stops caching via the secondary cache, but all outstandingI/Os are completed.Reconfiguring CacheCade Virtual DisksIn operating system management applications, the resizing of CacheCade virtual disks occurs without stopping anyexisting I/Os. Creating a new CacheCade virtual disk or adding one or more SSDs to an existing CacheCade virtual diskincreases the total cache size. The new resources are immediately used after the addition.There are two methods to reconfigure CacheCade virtual disks:• Automatic reconfiguration of cachecade virtual disks• Manual reconfiguration of cachecade virtual disksAutomatic Reconfiguration Of CacheCade Virtual DisksA CacheCade virtual disk that is made up of more than one SSD is automatically reconfigured upon a removal or failureof a member SSD. The virtual disk retains an Optimal state and adjusts its size to reflect the remaining number ofmember disks. If auto-rebuild is enabled on the controller, when a previously removed SSD is inserted back into thesystem or replaced with a new compatible SSD, the CacheCade automatically reconfigures and adjusts its size to reflectthe addition of the member SSD.The number of SSDs to be removed from a CacheCade virtual disk cannot equal the total number of SSDs currently inthe CacheCade virtual disk.After the automatic reconfiguration and resizing of a CacheCade virtual disk, the new virtual disk size is displayed inboth the BIOS Configuration Utility as well as in the OpenManage storage management application.CAUTION: If a disk is removed from a CacheCade virtual disk, the associated slot for that disk is a hot slot for theCacheCade volume. Any compatible disk inserted into that slot is automatically added to the CacheCade virtualdisk. Any preexisting data on that drive is lost.NOTE: Disks inserted into a CacheCade hot slot must be equal to or greater than the smallest contributing disk inthe virtual disk.Manual Resizing Of CacheCade Virtual DisksIn operating system management applications, a manual resizing of a CacheCade virtual disk occurs due to the additionor removal of drives. Reboot is not necessary.63
