Troubleshooting

Problem Diagnosis

When a problem exists with the multipath I/O, consult the Insight Management

Agents and do one of the following:

• For Microsoft operating systems:

— Use the ProLiant Storage Manager FAQs

— Use the ProLiant Storage Manager software and the Device Manager

Extension to identify I/O path status.

• For Linux operating systems, use the following command to identify HBA status,

multipath status, and I/O block transfer size:

cat /proc/mdstatus

Problems During Installation

This section provides systematic instructions on what to try and where to go for help

for the most common problems encountered during software installation.

If you encounter problems during installation:

1. In a Microsoft environment, be sure to uninstall any previous version of the

multipath software first. Refer to “Upgrade Procedures for Microsoft Operating

Systems” in Chapter 2, “Installation and Operation.”

2. Be sure that the firmware is upgraded for all of the HBAs and both of the HP

StorageWorks Modular Smart Array 500 controllers, if installed.
