Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion This section describes how to enable Virtual Sizing and set up your partitions to permit easy capacity expansion. For NetWare installations, plan ahead and consider your storage use. Since NetWare permits only one NetWare partition per logical drive, make the NetWare partition the size of the virtual logical drive in advance so that you can expand that volume. Under NetWare, you cannot grow a partition, but you can add additional segments within an existing partition. The added segments can be "joined" to be part of the same volume, or they can be made into separate volumes. NOTE If NetWare must be installed on the disk array, create a single logical drive with Virtual Sizing enabled. Create a DOS partition of 500 MB or less for booting. NetWare volumes can then be added after the DOS partition on the same logical drive. The unused space on the partition can be used later for capacity expansion. Be sure to follow the precautions above. In most installations, the operating system is installed on a SCSI drive connected outside of the HP NetRAID system. The following steps are necessary to prepare your array for capacity expansion. Setting Up Your Array for Capacity Expansion This section makes the following assumptions: • You have already configured your HP NetRAID system as discussed in Chapter 5. You should have created only one logical drive per array. For example, you might have four physical drives of 4 GB each. You might have configured these four drives as a single RAID 5 logical drive. This will produce a logical drive with 12 GB of real storage capacity, with 4 GB used for parity. • You have initialized your logical drives. 68
