Version 2.2.0.470

Version Identifier (VID) V01

Serial Number (SN)NFL2RJ8II98

ADE-OS Version 3.0.2.218

It's probably running into some issues with the disk or the file systems.

If it for your own lab, it could be quicker to de-register it and rebuild this ISE node. If it accessible from ESXi or vCenter or CIMC and if you may share the info, please unicast me the info so I can take a look.

If for production, please engage TAC.

this is in production. i can not  ssh or GUI login to check any thing in that. From the console( virtual Esix) what is the process (Commands) to dregister and reregister?

[hslai]

Registering and deregistering an ISE node is done at the admin web UI of the primary ISE node.

As you mentioned it production, please open a TAC case so TAC may help and look into deeper.
