HP 3PAR AIX and IBM Virtual I/O Server Implementation Guide

NOTE: HP recommends enabling the 3par_pathmon.sh script that is provided with HP 3PAR

ODM 3.1. This daemon-like program monitors the HP 3PAR device paths that are in a Failed

state. For all paths in a Failed state that the health check function cannot bring back, a chpath

command is issued to enable them. See the README provided with the HP 3PAR ODM 3.1 for

instructions and usage.

Displaying the Path Status After Installing HP 3PAR ODM

After the installation of the HP 3PAR MPIO for AIX HBA, verify that the HP 3PAR ODM has been

installed successfully:

# lslpp -l|grep -i 3par

3PARmpio.64 3.1.0.0 COMMITTED 3PAR Multipath I/O for IBM

After the installation of the ODM for AIX MPIO, check path status and verify the connection between

the host server and HP 3PAR StoreServ Storage.

• To display the FC device available on the AIX or IBM Virtual I/O Server host, issue lsdev

-Cc disk.

# lsdev -Cc disk

hdisk0 Available 00-08-00 SAS Disk Drive

• To display the path status through the AIX CLI on hdisk1, issue lspath –l hdisk1:

# lspath -l hdisk1

Enabled hdisk1 fscsi4

Enabled hdisk1 fscsi5

• To display the specific path information on hdisk1, issue lspath -l hdisk1 -F “status

name parent connection”.

NOTE: Highlighted text shows the details for node, slot, and port <n:s:p>.

# lspath -l hdisk1 -F “status name parent connection”
