Description

Error Message

No errors are indicated.

The command:

# /sbin/lltconfig -c

completes without any error.

The command:

# /sbin/lltconfig -V

which should show LLT version information, returns to the prompt with no output.

Verification of the package shows errors

# pkgchk VRTSllt

Most importantly:

ERROR: /sbin/lltconfig

    file size (264776) expected  (0) actual

    file cksum (1813) expected (0) actual

Cause

The file "/sbin/lltconfig" has a file size of zero bytes.

The file is corrupt, the filesize should be 264776 bytes (the expected value noted above).

Resolution

There are two possible solutions to the issue:

1) Replace the file by copying the /sbin/lltconfig file from a working cluster node.

-OR-

2) Remove and re-install the VRTSllt package on the node which is not working.

Once either 1 or 2 is completed, the cluster software should be able to successfully start on this node.

To start the cluster:

# /sbin/lltconfig -c

# /sbin/gabconfig -c -n2

Where fencing is in use:

# /sbin/vxfenconfig -c

# /opt/VRTS/bin/hastart

 


Issue/Introduction

A cluster node fails to join the cluster after a reboot. GAB (Group Atomic Broadcast) and subsequently HAD (High Availibility Daemon) cannot start on the system.
