Finding and correcting problems

This topic describes items to check to determine and correct problems in SAN File System.

  1. In the tank.properties files, the RSA_USER and RSA_PASSWD entries must be the same on all servers. If the values do not match, correct the values using vi editor and save the file. Be careful not to space after the last letter.
  2. Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
  3. Retry the tanktool lsengine command to see if connectivity is restored. The default values are: RSA_USER=USERID and RSA_PASSWD=PASSW0RD (zero not the letter O). You can change the values, but make the changes on all servers.
  4. If the RSA_USER and RSA_PASSWD information match on all servers, try to log into each RSA card user interface using the userid and password in the tank.properties files. From the Configuration File of each RSA card, you can view the Login Profile entries to see if there is an entry to match the data in the tank.properties files.
  5. If you cannot log in to a server or find a matching entry, add a new login profile.
  6. As a test, log out of the RSA user interface and back in using the new Login information.
  7. Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
  8. Retry the tanktool lsengine command to see if connectivity is restored.
    Note: Multiple Login profiles can exist, but at least one login profile must be the same on all servers; and each must match what is in all the tank.properties files. The Host operating system entry in the Configuration Summary File must say Linux. If it does not, the In Boot, Booting OS, and/or Wrong OS errors might appear and the ibmasm daemon might not start.
  9. To correct, in the left panel, select Server->ASM Control->System Settings->ASM Information.
  10. Select Linux from the Host operating system drop-down menu.
  11. In the left panel, select Restart ASM.
  12. Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
  13. Retry the tanktool lsengine command to see if connectivity is restored.
  14. If the command still gives an error, reboot the metadata server to start/restart the ASM daemon on the RSA card.
  15. Verify that the RSA cabling and configuration is correct. You can verify the information using the RSA Configuration Summary File. Refer to the SAN File System Planning, Installation, and Configuration Guide for more information.
