Depending on how you plan to use independent disk pools, you must have
the following software and licenses:
Multiple-system clustered environment
If
you plan to use switchable independent disk pools or independent disk pools
that are geographically mirrored, the following are required elements:
- You need OS/400® V5R1M01 or
later.
Note: For systems on the same HSL loop see, the
High
Availability Web site to ensure that you have compatible versions of i5/OS™ or OS/400.
- iSeries™ Navigator
is the graphical user interface for managing and administering your iSeries server
from your Windows® desktop. It is required to perform some
of the disk management tasks necessary to use independent disk pools. See iSeries Navigator requirements for disk management for steps to enable iSeries Navigator for disk management.
- You need to install Option 41 HA Switchable Resources. Option 41 gives you the capability
to switch independent disk pools between systems. To switch an independent
disk pool between servers, the servers must be members of a cluster and the
independent disk pool must be associated with a switchable hardware group
in that cluster. Option 41 also gives you the capability of using the iSeries Navigator
cluster management interface to define and manage a cluster that uses switchable
resources.
Single-system environment
- You need OS/400 V5R1M01 or
later.
- iSeries Navigator
is the graphical user interface for managing and administering your iSeries server
from your Windows desktop. It is required to perform some
of the disk management tasks necessary to implementing independent disk pools.
See iSeries Navigator requirements for disk
management for details.
1 OS/400 V5R1M0 can be used for implementing
independent disk pools containing user-defined file systems (UDFS) only.
Support for library-based objects is only available starting with OS/400 V5R2M0.
Support for geographic mirroring is available at OS/400 V5R3M0.
