• Increase raw data storage • Improve performance by increasing the number of spindles in a logical drive volume • Change fault-tolerance (RAID) configurations For more information about RAID levels, see the Smart Array Controller User Guide, or the document titled Assessing RAID ADG vs. RAID 5 vs. RAID 1+0. Both are available at the Smart Array controller web page or at http://h18000.www1.hp.com/products/servers/proliantstorage/arraycontrollers/ documentation.html. Extend volumes using Disk Management The Disk Management snap-in provides management of hard disks, volumes or partitions. It can be used to extend a dynamic volume only. NOTE: Disk Management cannot be used to extend basic disk partitions. Guidelines for extending a dynamic volume: • Use the Disk Management utility. • You can extend a volume only if it does not have a file system or if it is formatted NTFS. • You cannot extend volumes formatted using FAT or FAT32. • You cannot extend striped volumes, mirrored volumes, or RAID 5 volumes. For more information, see the Disk Management online help. Expanding storage for EVA arrays using Command View EVA Presenting a virtual disk offers its storage to a host. To make a virtual disk available to a host, you must present it. You can present a virtual disk to a host during or after virtual disk creation. The virtual disk must be completely created before the host presentation can occur. If you choose host presentation during virtual disk creation, the management agent cannot complete any other task until that virtual disk is created and presented. Therefore, HP recommends that you wait until a virtual disk is created before presenting it to a host. For more information, see the HP StorageWorks Command View EVA User Guide. Expanding storage using the Array Configuration Utility The Array Configuration Utility enables online capacity expansion of the array and logical drive for specific MSA storage arrays, such as the MSA1000 and MSA1500. For more information, use the ACU online help, or the procedures to "Expand Array" in the HP Array Configuration Utility User Guide Expand logical drive This option in the ACU increases the storage capacity of a logical drive by adding unused space on an array to the logical drive on the same array. The unused space is obtained either by expanding an array or by deleting another logical drive on the same array. For more information, use the ACU online help, or the "Extend logical drive" procedure in the HP Array Configuration Utility User Guide 66 File server management
