Software and licensing requirements

 

Depending on how you plan to use independent disk pools, have specific software and licenses.

If you plan to use switchable independent disk pools or independent disk pools that are geographically mirrored, the following elements are required :

• You need OS/400^® V5R1M0¹ or later.

  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 System i™ from your Windows^® desktop. It is required to perform some of the disk management tasks necessary to use independent disk pools. See 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 systems, the systems 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.

If you plan to use independent disk pools in a single-system environment, the following elements are required :

• You need OS/400 V5R1M0¹ or later.

• iSeries Navigator is the graphical user interface for managing and administering your system 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.
