Chapter 7 Preparing for Online Capacity Expansion Preparing for Online Capacity Expansion under NetWare 5.x About Capacity Expansion under NetWare 5.x 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 for online capacity expansion under NetWare 5.x is simply to leave virtual sizing disabled (the factory default), or to disable it if it has been enabled. Refer to the HP NetRAID Series User Guide and your NetWare 5.x documentation for information about online capacity expansion. Planning for Online Capacity Expansion under NetWare 5.x To permit easy capacity expansion of a NetWare 5.x installation, plan ahead and consider your storage use. • Under NetWare 5.x, 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.x, 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.x. NOTE If NetWare 5.x must be installed on the HP NetRAID disk array, create a single logical drive with virtual sizing disabled. 87

About Capacity Expansion under NetWare 5.x
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 for online capacity expansion under NetWare 5.x is simply to leave
virtual sizing disabled (the factory default), or to disable it if it has been enabled.
Refer to the HP
NetRAID Series User Guide
and your NetWare 5.x
documentation for information about online capacity expansion.
Planning for Online Capacity Expansion under NetWare 5.x
To permit easy capacity expansion of a NetWare 5.x installation, plan ahead and
consider your storage use.
•
Under NetWare 5.x, 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.x, 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.x.
NOTE
If NetWare 5.x must be installed on the HP NetRAID disk
array, create a single logical drive with virtual sizing disabled.
