Chapter 7 Preparing for Online Capacity Expansion At this point, the logical drive has a NetWare partition of 144 GB with a 12-GB segment set as a volume. The 12-GB volume is mounted and ready for use. Be sure not to exceed the actual physical capacity when creating the 12-GB volume and include other uses such as a Hot Fix area. The new volume is now ready for use. Assume for this example, the volume is called VOL1. Leave the remaining virtual storage space (144 GB minus 12 GB) as unused. You can write data up to 12 GB on the drive. Create Volumes on Drives that Contain NetWare Sometimes it is desirable to have the network operating system reside on a disk array. The advantage is that the NOS resides on a redundant drive. Virtual Sizing can be used with a disk array that is used as the boot device and also contains user data. If NetWare must be installed on the disk array, follow these steps: 1. Create a DOS partition of 500 MB or less for booting. 2. Create additional NetWare volumes after the DOS partition on the same logical drive for data. 3. The remaining virtual capacity must be left unpartitioned, and will be available for future partitions as you add disk drives to the array. NOTE Be sure not to create volumes that exceed the actual physical capacity. You must add up the capacities of all volumes that may be using the physical storage space such as a DOS volume, SYS volume, Hot Fix Area, and any user volumes. Online Capacity Expansion Under Windows NT Theory of Operation Normally, adding capacity requires shutting down the server to reconfigure/restore an existing volume or to add the new storage space as a new volume. Using the Online Capacity Expansion feature allows you to expand an existing logical drive without shutting down the server. 71
