Symptoms

CELL-07501 errors are reported in your cell server logs. You would like to verify if these errors are resolved or outstanding.

The CELL-07501 error is usually preceded by another alerthistory update which outlines the problem. This alerthistory entry may have the "Severity: clear" designation, which means that the underlying issue is now cleared or resolved.

For example you might see in the file /opt/oracle/cell/log/diag/asm/cell/exacel02/trace/ms-odl.trc:

Use the following commands to determine if there is an issue with the cell server:

1. CellCLI> alter cell validate configuration

A successful output would be:

CellCLI> alter cell validate configuration
Cell exacel02 successfully altered

2. /opt/oracle.SupportTools/CheckSWProfile.sh -c

A successful output would be:

[root@exacel02 ~]# /opt/oracle.SupportTools/CheckSWProfile.sh -c

[INFO] SUCCESS: Meets requirements of operating platform and InfiniBand software.
