Cause

Fails to run Supportsave and license install due to error: 
 "The switch does not have enough disk space to run full supportsave. Available Free disk space is 0 MB."
  
Switch-A:admin> supportsave
This command collects RASLOG, TRACE, supportShow, core file, FFDC data
and then transfer them to a FTP/SCP/SFTP server or a USB device.
This operation can take several minutes.
OK to proceed? (yes, y, no, n): [no] yes
Host IP or Host Name: 10.82.50.27
User Name: username
Password: ******
Protocol (ftp | scp | sftp): sftp
Remote Directory: /home/inti/brocade
Do you want to continue with CRA (Y/N) [N]:
The switch does not have enough disk space to run full supportsave. Available Free disk space is 0 MB.
Please run the following commands to release disk space and retry full supportsave
1. "supportsave -k" to transfer core files to remote location
2. "supportsave -R" to remove the core files in the switch
SupportSave failed.
Look for core files to be deleted from the below command: 
Switch-A:admin> supportsave -R
No core or FFDC data files found!
SupportSave completed.

Resolution

There are several possible ways to address this issue:
  • Fix 1:
  1. Run the below command to confirm if root account is enabled.
 userconfig --show root
  1. Using root account, remove /var/log/esmd_lib.log files which may be taking more flash memory
  1. Capture the output of the below command from root.
root> ls lR /var
In this output, you should see the following: 
/var/log:

-rw-r--r--   1 root     root      3113586 Oct 14 11:16 esmd_lib.log
-rw-r--r--   1 root     admin    14065977 Oct 13 05:17 esmd_lib.log.1
-rw-r--r--   1 root     admin    82593068 Oct  7 11:04 esmd_lib.log.2
-rw-r--r--   1 root     root     329366414 Sep  2 13:41 esmd_lib.log.3
  1. Issue the following commands from root to remove the files
rm /var/log/esmd_lib.log
rm /var/log/esmd_lib.log.1
rm /var/log/esmd_lib.log.2
This cleans up Flash Memory and allows the supportsave to be run.
  1. Collect supportsave and install license using licenseadd <key> command after cleaning up flash memory.
  2. If the root account is enabled, run the below command which removes temp and unwanted firmware files.
df -k
 
If the root account is not enabled, you may be unable to enable due to memory issue. Follow fix 2 if the root account is disabled. 
Switch_A:admin> userconfig --show root
Account name: root*
Description: root
Enabled: No
Password Last Change Date: Unknown (UTC)
Password Expiration Date: Not Applicable (UTC)

Switch_A:admin> userconfig --change root -e yes

Failed to change user account attributes
  • Fix 2:
  1. Take backup of configuration and perform Hareboot under maintenance window to clear flash memory issue.
  2. After performing Hareboot, collect supportsave logs and try to install the license using licenseadd <key> command.
  • Fix 3:
If Fix 2 fails to clear flash memory or enable root account, engage the Switch vendor for further assistance prior to performing a switch replacement.
