4 Change and or verify that the InServ Storage Server port personas or host personas are set
depending of the InForm OS version running, as described in This section describes how to
configure InServ Storage Server ports running OS 2.3.X. and 2.1.1 Configuring Ports for a
Direct Connection or 2.1.2 Configuring Ports for a Fabric Connection.
5 Issue the inst3par.sh script
./inst3par.sh. (The script is directly accessible from the /
cdrom directory).
6 In order for the results to be permanent, execute the <savebase> and <bosboot -a>
commands. Observe caution when executing these two commands. Please refer to AIX
documentation for details.
7 Reboot the AIX system after executing the
bosboot command and waiting for command
completion to occur.
8 If the AIX system had previously defined InServ Storage Server VVs, the hdisk definitions
appear as
3PAR InServ Virtual Volume. Any newly created or exported InServ
Storage Server VVs will also have characteristics similar to those shown below:
Existing 3PAR virtual volumes or any newly created or exported InServ Storage Server VVs has a
default queue depth of 16 defined. To display this value, issue the following command on the
AIX CLI, where x is the
hdisk number/definition.
If required, changes may be applied to the new default queue depth of the InServ Virtual
Volumes. Any change made to the queue depth requires a system reboot to become effective.
To change the device attribute for queue depth issue the following command on the AIX CLI:
# lsdev -C -c disk
