Excerpt of the licenses installed in the affected InfoScale 7.4 server:

3 licenses of Infoscale Enterprise are copied to /etc/vx/licenses/lic.

-rw-r--r--. 1 root root 4881 Oct  4 08:22 XXXXXXXX_QTY4_VRTS_IS_ENT_7_4_UNX_XXXXXXXXX.slf 

-rw-r--r--. 1 root root 4881 Oct  4 08:22 XXXXXXXX_QTY4_VRTS_IS_ENT_7_4_UNX_XXXXXXXXX_1.slf

-rw-r--r--. 1 root root 4881 Oct  4 08:22 XXXXXXXX_QTY4_VRTS_IS_ENT_7_4_UNX_XXXXXXXXX_2.slf

Reason:

With Infoscale 7.4 or 7.4.1:

1. It is not recommended to copy the license keys to /etc/vx/licenses/lic directory.
2. we can have only 2 of the same product licenses at any point in time.

1. Remove all the keys existing keys under /etc/vx/licenses/lic directory:

For example on InfoScale 7.4

#cd /etc/vx/licenses/lic

#mv xxxxxxxxxxx_QTY4_VRTS_IS_ENT_7_4_UNX_XXXXXXXXX_1.slf /var/tmp  >> do it for all the licenses visible under the directory

2. Install the new license key using the following command:

# /opt/VRTSvlic/bin/vxlicinst -k

3. Once the license key is successfully installed, if running InfoScale 7.4 you should then see the below entry under /etc/vx/licenses/lic

[root@server101 lic]# ls -l
total 16
-rw-r--r--. 1 root root 4881 Oct  4 08:22 XXXXXXXX_QTY4_VRTS_IS_ENT_7_4_UNX_XXXXXXXXX.slf

Restarting HAD/vxconfigd will not result in core dump.

Note : We need to use vxlicinst or vxlicinstupgrade commands to add permanent license keys to the server.
