Chapter 6 Capacity Expansion 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 also 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. Expanding Capacity Online under NetWare 4.2 After using a logical drive, you might want to add another physical drive. If you prepared the logical drive for Online Capacity Expansion, this can be done without shutting down the server or restarting the system. In the example used throughout this section, you might be nearing the 12-GB limit, and you want to add another 4-GB drive to the existing array. To expand capacity online, follow the instructions later in this section to do the following: • First: Install the added physical capacity into the internal hot-swap mass storage cage or into the external enclosure. • Second: Use the HP NetRAID Config utility to reconstruct the logical drive to include the added capacity. For instructions, refer to "Second, Reconstruct to Add Capacity" later in this section. • Third: In NetWare 4.2, create a new volume consisting of the added capacity and make that new free segment part of the existing volume. For instructions, refer to "Third, Add Capacity in NetWare 4.2" later in this section. 114

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
also 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.
Expanding Capacity Online under NetWare 4.2
After using a logical drive, you might want to add another physical drive. If you
prepared the logical drive for Online Capacity Expansion, this can be done
without shutting down the server or restarting the system.
In the example used throughout this section, you might be nearing the 12-GB
limit, and you want to add another 4-GB drive to the existing array.
To expand capacity online, follow the instructions later in this section to do the
following:
•
First:
Install the added physical capacity into the internal hot-swap mass
storage cage or into the external enclosure.
•
Second:
Use the HP NetRAID Config utility to reconstruct the logical
drive to include the added capacity. For instructions, refer to "Second,
Reconstruct to Add Capacity" later in this section.
•
Third:
In NetWare 4.2, create a new volume consisting of the added
capacity and make that new free segment part of the existing volume. For
instructions, refer to "Third, Add Capacity in NetWare 4.2" later in this
section.
