Grid Engine Master Cannot Be Unloaded From N1 System Manager When Two Masters Are Present (6423617)

Workaround: Reload N1 System Manager or remove one of the master hosts from the database by performing the following procedure.

1. Access the database through /opt/SUNWscs/sbin/db_tool.pl psql for Solaris or /opt/sun/scs/sbin/db_tool.pl psql for Linux.

2. List the entries for the two masters:

   mgmt=>select * from sge_hosts;

   appliance_id | type | hostname | spooldir --------------+--------+-----------+------------------------------------- 2 | MASTER | 10-0-0-17 | /gridware/sge/default/spool/qmaster 3 | MASTER | hdco16 | /gridware/sge/default/spool/qmaster (2 rows)

   mgmt=>SELECT * from sge_host_versions;

   appliance_id | version --------------+--------- 2 | a1 3 | a1 (2 rows)

3. Delete one of the masters from the sge_host_versions table and the sge_hosts table.

   mgmt=>delete from sge_host_versions where appliance_id = '3';

   DELETE 1

   mgmt=>SELECT * from sge_host_versions;

   appliance_id | version --------------+--------- 2 | a1 (1 row)

   mgmt=>delete from sge_hosts where appliance_id = '3';

   DELETE 1

   mgmt=>select * from sge_hosts;

   appliance_id | type | hostname | spooldir --------------+--------+-----------+------------------------------------- 2 | MASTER | 10-0-0-17 | /gridware/sge/default/spool/qmaster (1 row)
