Host Boot from an InServ Storage Server
NOTE: Once 3PAR MPIO 2.2 for IBM AIX has been installed, it cannot be de-installed for a host
boot disk.
AIX host boot is supported by the InServ Storage Server. However, in order to successfully install the
AIX operating system on InServ volumes, the following steps must be followed:
1. Configure the InServ Storage Server to the AIX system. Refer to the 3PAR Best Practice
documents for IBM AIX for detailed instructions.
NOTE: Restrict a single path connection between the InServ Storage Server and the AIX host
system.
2. Install the AIX operating system on the selected InServ volume.
3. Reboot the AIX system. The InServ volume is configured as an MPIO capable device with the AIX
default PCM. Upgrade the AIX operating system to the recommended maintenance level. Refer
to the 3PAR Best Practice documents for IBM AIX for detailed instructions.
4. Install the 3PAR MPIO 2.2 for IBM AIX.
5. Execute bosboot –aDd /dev/ipldevice.
6. Reboot the AIX system.
7. After the AIX system comes up completely, connect additional paths to the Fabric or the 3PAR
disk storage system. Configure additional paths.
• Examples of configuring additional paths:
/usr/lib/methods/cfgefscsi –l fscsiX
In the example above, X is the additional path’s FC SCSI controller protocol device.
cfgmgr –vl hdiskX
In the example above, X is the InServ volume for the host boot.
• Example of displaying multiple paths:
lspath –l hdiskX
In example above, X is the InServ volume for the host boot
8. Execute bosboot –aDd /dev/ipldevice.
9. Reboot the AIX system.
All InServ volumes, including the selected InServ boot volumes, are now configured with the 3PAR
PCM.
