This topic describes items to check to determine and correct problems
in SAN File System.
- 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.
- Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
- 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.
- 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.
- If you cannot log in to a server or find a matching entry, add a new login
profile.
- As a test, log out of the RSA user interface and back in using the new
Login information.
- Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
- 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.
- To correct, in the left panel, select Server->ASM Control->System
Settings->ASM Information.
- Select Linux from the Host operating system drop-down menu.
- In the left panel, select Restart ASM.
- Run the following commands: stopCimom, startCimom, stopConsole, startConsole. These commands are located in /usr/tank/admin/bin.
- Retry the tanktool lsengine command
to see if connectivity is restored.
- If the command still gives an error, reboot the metadata server to start/restart
the ASM daemon on the RSA card.
- 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.
