Recovery from failed firmware update for IBM 2005-B64 / Brocade 4900?

Hello,

we tried to upgrade Firmware on a IBM 2005-B64, Brocade 4900 from V5.3.2A to 6.0.0.C using DCFM_Pro10_4_5.

After about 10 minutes the switch disconnected Ethernet and ISL-Trunks and did not come up for about an hour when we decited to power cycle the device.

As one would expect (would be afraid of): "OSRootPartition: both boot devices are inconsitent". A repair attempt sbin/... failed.

Having access to the boot loader (Boot PROM 4.6.5) only I have the following questions:

1) Is there any boot ENET option by which I could reinstall a v5.3.2A from a bootp/tftp server? How would the procedure look like?

2) Is there any possibility to repair the Compact Flash off-line (using Linux and a CF-card reader)?

3) Is it really such that one would loose a 80.000 EUR/USD device just by a failed firmware update and need to replace it completely without any chance to repair the Flash? That would be very sad indeed.

Any help appreciated,

Karsten

--->>>1) Is there any boot ENET option by which I could reinstall a v5.3.2A from a bootp/tftp server?

Net_Install Package is available from Brocade if you have a valid Maintenance Contract.

--->>>After about 10 minutes the switch disconnected Ethernet and ISL-Trunks....

This is a normally Upgrade procedure, whic hrequiered beetwen 10 and 30 Minutes.

In such case the error was caused by malconfigured FTP Access, Firewall behind, and in most case Dump's was available in the switch.

Such Dumps must be removed before"firmwaredownload" started.

You can try to connect trough serial Port, and boot the Switch from Secondary MEM Partition.

Hi,

When a FW upgrade is performed, initially the new FOS is installed in the secondary flash partition; then, the switch internally failovers from the Active partition (with old FOS) to the Secondary partition (with new FOS); and once this is done the new FOS is copied to the new secondary partition. If something happened to the new FOS image and the switch does not start, you could try to connect via Serial to the switch and change the boot partition, so that it starts from the other one.
