Chapter 6 Capacity Expansion

•
Expanding Capacity under NetWare 5 with Virtual Sizing Enabled
describes how you can add disk capacity to an existing logical drive if you
did not prepare your logical drive initially to use the Online Capacity
Expansion feature.
About Online Capacity Expansion under NetWare 5
Normally, to add capacity you must shut down the server to reconfigure and then
restore data, or you must add the new storage space as a new volume. The Online
Capacity Expansion feature allows you to expand an existing logical drive without
shutting down the server.
The Online Capacity Expansion feature cannot be used if a logical drive spans
multiple arrays. Each array can contain only one logical drive. Reconstruction (for
the purposes of adding a drive to an existing array) can only be done on an array
having a single logical drive. It is also important to plan future storage expansion
into your installation. This will ensure that you can easily expand capacity without
backup/restore operations or reconfiguration.
Preparation of the logical drive for Online Capacity Expansion under NetWare 5
is simply to leave Virtual Sizing disabled (the factory default), or to disable it if it
has been enabled.
Planning for Online Capacity Expansion under NetWare 5
To permit easy capacity expansion of a NetWare 5 installation, plan ahead and
consider your storage use.
•
Under NetWare 5, you cannot grow a partition, but you can add additional
partitions within an existing logical drive. The added volumes can be
"joined" to be part of the same volume, or they can be made into separate
volumes.
•
Under NetWare 5 you can expand the capacity of a logical drive three
times online before you need to go offline to expand its capacity a fourth
time. The fourth expansion involves backing up your data and restoring it.
Then you can expand online three more times before you need to go offline
for the next expansion, and so forth.
•
NSS volumes are not supported in NetWare 5.
NOTE If NetWare 5 must be installed on the HP NetRAID disk array,
create a single logical drive with Virtual Sizing disabled.
