Upgrading Software
OSW, <OSWFileName>, found in the Flash File System. The OSW has not been
updated from this file due to insufficient Flash File System space.
Please delete unnecessary files from the system.
It is possible that you will not have enough room in the \
SYSTEM
directory to TFTP the
upgrade file to the system. In this case:
•
Delete all files in the directory except
nex.bin
and
iop.bin
.
•
Issue a
flash reclaim
command to gain the lost space (this will destroy the backup
copy of your configuration, you will be unable to issue restore command unless you
have saved at least one set of changes).
•
If the upgrade still fails, delete the
nex.bin
and
iop.bin
and again reclaim the space.
Your upgrade should now work. IMPORTANT: Do not restart the CyberSWITCH until
the upgrade is complete.
If you are upgrading from a previous version of system software, the above message will
not be displayed. In this case, the system continually restarts, attempting to install the OSW
package each time.

(SSB)
WARNING:
If power is lost on the remote CyberSWITCH during this process, a local upgrade of the
SSB may be necessary before the system can again function.
To remotely upgrade the SSB, follow these steps:
1.
Telnet to the CyberSWITCH and login as admin.
2.
Enable
TFTP
, the TFTP client, and the TFTP server with admin access rights.
3.
Using the TFTP client on the remote workstation, TFTP the
recover1
file to the
CyberSWITCH in binary mode. Be sure to use the file’s full pathname (for example:
D:\CSX156\JAPAN\IPIPX\RECOVER1)
. The exact method to transfer varies, depending
upon your TFTP client.
4.
At the system prompt, recover the SSB by issuing the following command:
flash recover
The system will ask you if you are sure you want to remotely recover the SSB, and warn you
of the potential risk in case of a power failure while the SSB is being recovered. Answer “yes”
to the prompt. The window of vulnerability ends after 5 or 10 seconds, when the system tells
you that the SSB was successfully recovered.
5.
After the recovery, delete the file by issuing the command:
del \system\recover1
6.
Recover lost space with the command:
flash reclaim
