The new volume is now ready for use.
Assume, for example, that the volume is called VOL1 and that its physical
capacity is 12 GB. Its partition is 144 GB. 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 4.2
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.
NOTE
A NetWare 4.2 SYS volume should be limited to 2 GB or to a
smaller size appropriate for your system. Use the balance for a
user volume.
Virtual sizing can be used with a disk array that is used as the boot device and
contains user data. If NetWare 4.2 must reside 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. Do not exceed the physical space capacity. Create
these volumes as described in "Create Volumes on Drives that do not
Contain NetWare 4.2."
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.
