CELL-02630: There is a communication error between Management Server and Cell Server caused by a mismatch of security keys. Check that both servers have access to and use the same $OSSCONF/cellmskey.ora file.

IHAC who is on Exadata image version: 11.2.3.3.0.131014.1, faced below issue.

Any command on cellcli was failing with error: CELL-02630.

CELL-02630: There is a communication error between Management Server and Cell Server caused by a mismatch of security keys. Check that both servers have access to and use the same $OSSCONF/cellmskey.ora file.

If you read error description, it refers to communication error between CELLSRV & MS processes, due to mismatch in security keys.

I did check current status of CELL process & all were up & running.


[root@test01celadm01 ~]# service celld status
rsStatus: running
msStatus: running
cellsrvStatus: running

MS always creates key file ==> cellmskey.ora on startup if it does not exist. But in our case it was not present. (Not sure if someone deleted it manually)

I asked customer to restart MS process & check if it helps. After restarting MS process, CELLCLI commands started working as expected 🙂


CellCLI> alter cell restart services ms

Restarting MS services...
The RESTART of MS services was successful.

CellCLI> list celldisk
