Connectrix Cisco MDS-Series: NX-OS temp file filling up expect to crash against the ESRS plugin script issue. NX-OS 7.3(1) NX-OS 8.2(1)

The fix has been added to the ESRS plugins.

Problem:
NX-OS temp-file is filling up, and expect to crash the switch against the ESRS plugin script.
The ESRS plugin scripts fills up the temp directory and space on the switch which might results in NXOS crash.

Environment:
Cisco software: NX-OS 7.3(1)
Cisco software: NX-OS 8.2(1)

To check how much space is free:
Example:
switch9132T# dir bootflash:
       4096    Jan 09 02:27:40 2017  .partner/

To check the size of the temp-file  and the free space:

The old scripts keeps on creating a temp which is not deleted and is filling up the memory space.

Fix:

1. Remove the existing scripts that are mapped to alert group using below command:
 # conf t
   conf #callhome
   callhome#  no alert_group <XXX> script-name  <script-name.tar> (specify the alert group that you need to disable)
    callhome# commit
Below is the list of available alert groups:
SVT9132T(config-callhome)# no alert-group
All                   Inventory             Supervisor-Hardware
Cisco-TAC             License               Syslog-group-port
Crash                 Linecard-Hardware     System
Environmental         RMON                  Test

select all alert groups individually to which the old scripts are mapped.

2. Download the new scripts from support.emc.com site. They are the scripts which contains the fix for the issue.
3. Do the necessary changes on the new scripts as per the old one. Download the procedure from SolVe on how to configure the esrs plugin scripts.
4. Place the new scripts on the switch.
5. Enable the plugin on the switch. The process is available in the SolVe on how to enable ESRS plugin on the MDS switches. 

Note that the new scripts will delete the old files automatically, no extra activity is needed.

To be able to check what date on the installed script, one can do the following command to check the dates:
Example:
switch9132T# dir bootflash://sup-active/scripts
     108032    Mar 21 03:04:13 2017  ch_script_9132T.tar
     108544    Oct 06 11:06:47 2017  ch_script_9132T_822.tar
     109568    Jan 15 02:59:05 2018  ch_script_9132T_831_new.tar
     109056    Dec 13 01:38:31 2017  ch_script_9132t_8_2_2_updated.tar
