If the Availability Status on the Viewing Clusters page
is No Contact, the cluster either does
not exist or is offline, or there is a network problem.
Also, node error 540 might be displayed on the front panel
on the SAN Volume Controller node.
Perform the following actions to make the cluster available:
Note: Click Refresh after
each step.
- Restart the IBM® System Storage® Productivity
Center (SSPC)
or master console server.
- If the Availability status is still No
Contact, open a command prompt from the SSPC or master console server
and ping the IP address of the cluster. You can view the
IP address either from the SAN Volume Controller Console screens
or the front panel of the SAN Volume Controller node.
- If you can successfully ping the SSPC or master console server,
run the CLI command to check the cluster status. Otherwise, see MAP 5500: Ethernet. If those
procedures do not solve the problem, contact the IBM Support
Center for
assistance.
- If the Availability status is still No
Contact, the connection between the SAN Volume Controller Console and
the cluster might have been corrupted. Contact the IBM Support
Center.
