Common NIM Error codes

608 – tftp retrieve of client info file failure

Action If a 608 hang is encountered, verify that the file exists in the /tftpboot directory. If it does not exist, retry the NIM operation to create it. If it does exist, verify that tftp access to the /tftpboot directory is not restricted in the /etc/tftpaccess.ctl file. is also possible that the network adapter was not configured properly in the boot environment

611 – Remote mount of NFS file system failure

Action 611 hangs occur when the client machine is unable to mount a resource from a server. Ensure that NFS is running on the resource server. Verify that the resources specified for the operation are exported properly by checking the /etc/exports and /etc/xtab files on the server. Also, confirm that the resources have permissions set correctly for reading.

613 – Failure setting up route tables

Action 613 hangs usually occur because a route is incorrectly defined for a network in the NIM database. Verify that the correct gateways are specified between networks, and all gateways are functional. Use debug-enabled network boot images to determine which routes could not be defined.
