Hardware and Software Compatibility

FCA/HBA Compatibility

This EVM host agent supports the HP A5158A and A6795A Fibre Channel host bus adapters (FCA/HBA).

Platform Specific Considerations

The following issues are specific to the HP-UX platform and should be taken into account when planning EVM job operations:

• Initial LUN Requirement for HSG80 Controllers

• Default Configuration Supports 10 Volume Groups

Initial LUN Requirement for HSG80 Controllers

The HSG80 array controller does not maintain active or “online” connections to an HP-UX host unless a LUN is presented to that host at all times. The lack of online connections to a host can result in EVM job failures with an error message of “No usable mount connections found.” To prevent this problem, make sure that at least one LUN is presented to all HP-UX hosts to act as a mount-on host for EVM jobs.

Default Configuration Supports 10 Volume Groups

for HP-UX

With the default configuration, HP-UX supports a maximum of 10 volume groups. Because each EVM replication job creates a new volume group on the mount-on host, systems at or near the maximum number might experience job failures. To prevent this problem, use the “kmtune” utility to increase the number of supported volume groups to an appropriate level.

5Release Notes – Enterprise Volume Manager (Multi-OS) Host Agent Version 2.0D

Limitations and Known Issues

This section is an extension of a similar section in the HP StorageWorks Enterprise Volume Manager (Multi-OS) Version 2.0D Network Administration Guide

(AA–RR0VB–TE) and can help avoid problems while using EVM V2.0D. These topics are grouped in the following categories:

• Limitations, page 6

• Known Issues, page 10

Limitations

EVM limitations include the following topics:

• RTE/Browser Versions to Correct GUI Problems

• Logical Volume Manager Support

• BCV Persistence Across Host Reboots

• Mounting Multiple Logical Volumes per Volume Group

• International Language Support

• 30-Minute Spawn Process Timeout

RTE/Browser Versions to Correct GUI Problems

EVM requires the Java runtime environment (RTE) plug-in version to be installed on any host being used to view the EVM GUI (refer to the EVM Network Administration Guide for a list of supported browser and RTE versions). This RTE version appears to be compatible with most Microsoft Internet Explorer and Netscape Navigator browser versions, but some combinations result in unusual GUI behavior. Symptoms include:

• Job names being replaced by the word “null.”

• Unresponsiveness to double-clicking or right-clicking.

• Distorted displays and other abnormalities. If any of these problems are encountered:

1. Verify that only the required RTE version is installed on the host.

2. Remove any other versions, if necessary.

1. Hereafter referred to as EVM Network Administration Guide.
