ERROR: sfcfs_mount:0007:special : Cannot get host address of hostname for [P-MDS | S-MDS], not found in /etc/hosts

Explanation

The host name information for AC-to-MDS communication cannot be obtained.

Response

Check following points:

• Setting of network is normal.
  Check whether the IP addresses of the MDS nodes are correctly registered in host database (such as /etc/hosts). For details, see "11.2.2 Registering information in host database."

• The file system configuration information is normal.
  Execute sfcrscinfo(8) with the -m option to check whether the host names of the MDS nodes are correct.
  If the host names are not correct, change them by using sfcadm(8) with the -u option.

If the problem cannot be solved after taking the above actions, collect a file output with FJQSS, fjsnap, or pclsnap for troubleshooting information then contact field engineers.

For details on the commands, see sfcrscinfo(8) and sfcadm(8) in this manual.

• The shared node fails during command execution.

Response

Execute sfcmount(8) again after correcting the cause of the failure according to the following procedures:

• Check whether a file and a directory specified with special and mountpoint exist. If the specification is not correct, specify the correct special and mountpoint. Create the directory specified with mountpoint, if it has not been created.

• Check whether the IP address of the node that shares the file system is correctly registered in host database (such as /etc/hosts). For details, see "11.2.2 Registering information in host database."

• Execute sfcinfo(8) with the -n and -a options to check whether the host name of a shared node is correct. If the host name is not correct, change it by using sfcadm(8) with -u option.

• If any warning message was output immediately before this message, take an action to deal with the warning message.

If the problem cannot be solved by the response above, collect the diagnostic data FJQSS, fjsnap, or pclsnap, and contact field engineers.
