Planning For Online Capacity Expansion Under Netware 4.2 - HP P3410A - NetRAID 1M RAID Controller Installation And Configuration Manual

Chapter 7
NOTE
SFT-3 and mirroring users: Novell's operating system,
which provides system level fault tolerance by mirroring two
systems, is not compatible with the Online Capacity
Expansion feature. SFT-3 mirrors disk storage on a partition
basis rather than a volume basis. Because of the virtual space
created within the partition, SFT-3 cannot successfully mirror
the partitions. This limitation also applies to regular mirroring
(without SFT-3) of volumes. SFT-3 users may add storage
capacity online without bringing the two systems down if
enough drives are added to create a new array and logical
drive on an integrated HP NetRAID controller. Under the
Install module, NetWare 4.2 can then scan for new devices
and detect the new logical drive.

Planning for Online Capacity Expansion under NetWare 4.2

To permit easy capacity expansion of a NetWare 4.2 installation, plan ahead and
consider your storage use.
Since NetWare 4.2 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 4.2, 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.
NSS volumes are not supported in NetWare 4.2.
NOTE
If NetWare 4.2 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. However, NetWare can reside on a disk array
in the HP NetRAID system to achieve redundancy.
