Supported environment
Not all hardware and software combinations for OS/400 support the DS6000. This section describes the hardware and software
Hardware
The DS6000 is supported on all iSeries models which support Fibre Channel attachment for external storage. Fibre Channel was supported on all model 8xx onwards. AS/400 models 7xx and prior only supported SCSI attachment for external storage, so they cannot support the DS6000.
There are two Fibre Channel adapters for iSeries. Both support the DS6000:
2766 2 Gigabit Fibre Channel Disk Controller PCI
2787 2 Gigabit Fibre Channel Disk Controller
Each adapter requires its own dedicated I/O processor.
The iSeries Storage Web page provides information about current hardware requirements, including support for switches. This can be found at:
Software
The iSeries must be running V5R2 or V5R3 (i5/OS) of OS/400. In addition, at the time of writing, the following PTFs are required:
V5R2
–MF33327, MF33301, MF33469, MF33302, SI14711 and SI14754
V5R3
–MF33328, MF33845, MF33437, MF33303, SI14690, SI14755 and SI14550
Prior to attaching the DS6000 to iSeries, you should check for the latest PTFs, which may have superseded those shown here.
Logical volume sizes
OS/400 is supported on DS6000 as Fixed Block storage. Unlike other Open Systems using FB architecture, OS/400 only supports specific volume sizes and these may not be an exact number of extents. In general, these relate to the volume sizes available with internal devices, although some larger sizes are now supported for external storage only. OS/400 volumes are defined in decimal Gigabytes (109bytes).
