Support for fibre-channel boot
The following sections describe the prerequisites, the types of IBM RS/6000 or IBM
pSeries hosts that are supported, and required level of adapter microcode.
Prerequisites for setting up the IBM pSeries host as a fibre-channel
boot device
This section contain prerequisites for setting up the IBM pSeries host as a
fibre-channel boot device
Note: RS/6000 supports fibre-channel boot with or without SDD. However, if you
are using SDD with RS/6000 SP, you must install APAR IY37451.
Before you can set up the RS/6000 or IBM pSeries as a boot device, you must
meet the following prerequisites:
v An IBM pSeries or IBM RS/6000 system with the correct level of firmware
For the most current list of IBM RS/6000 or IBM pSeries hosts that are
supported, see the Interoperability Matrix at
http://www.ibm.com/servers/storage/disk/ds6000/interop.html.
v
Feature code 5716 at the correct microcode level and requires AIX 5.2H, AIX 5.3,
or higher.
v Feature code 6228 at the correct microcode level.
v Feature code 6239 needs to be at the correct microcode level and requires AIX
5.1 ML04 and above.
v AIX 5.1
For the SP, PSSP must be at 3.2 with APAR IY22732 (included in PSSP 3.2 PTF
14).
v A copy of the devices.fcp.disk.ibm.rte file.
For the most current microcode and firmware levels, see the Interoperability Matrix
at http://www.ibm.com/servers/storage/disk/ds6000/interop.html.
Fibre-channel boot considerations for IBM pSeries hosts
This topic lists fibre-channel boot considerations for IBM pSeries hosts.
Before you plan and use fibre-channel, consider the following items:
v
You must define the rootvg for each host.
When a volume group is varied online, a reserve is placed on all disks in the
group. For rootvg, this group is not released. You cannot share a rootvg volume
between hosts even when you shutdown all the hosts except one.
v You can create only one path to the rootvg volume during the installation.
v
If you use the multiboot, scanning for bootable disks takes much longer with a
large number of accessible storage elements in the Storage Area Network.
v Mirror the root volume group (rootvg)
By mirroring the storage unit root volume group, the base functionality and
reliability of the operating system for the storage unit is not affected.
