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:

switch9132T# dir log:

Cause

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

 

Resolution

Fix:

  1. Remove the existing scripts that are mapped to the 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 must 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 the support.emc.com site. They are the scripts which contain 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: The new scripts delete the old files automatically, no extra activity is needed.
