Cause
This issue occurs by the hardware monitoring service (dcism) that populates the /etc/cim/dell/srvadmin/iSM/ini directory.
Resolution
Engage with DellEMC support for a resolution with dcism vib.
Workaround
To workaround this issue:1. Connect to the ESXi host using SSH.2. Run this command to stop the dcism service: /etc/init.d/dcism-netmon-watchdog stop3. To ensure that the dcism does not start upon reboot chkconfig dcism-netmon-watchdog off4. Manually delete the files in the Check /etc/cim/dell/srvadmin/iSM/ini directory to free inodes. Such as tttttttttttttSQfKaqttttttttttttt8Rcadp5.Connect the ESXi back to vCenter if host does not come back into vCenter a reboot is required.
