Steps for repairing
: vdx reboot loop, vdx boot loop, vdx corrupt filesystem, vdx corrupt file system, vdx corrupt compact flash, vdx reboot loop after upgrade
Starting with NOS 6.x, firmwarecleaninstall is no longer a reliable method to recover switches. So, the preferred method now is to use netinstall.
The netinstall process will re-partition and format the switch's compact flash. So, all existing data on the local switch's compact flash will be erased!
Netinstall will install the firmware like a new switch. This can be useful when a switch is experiencing the following issues and it will take too long to fix manually:
- One of the GOS partitions (SW/0 or SW/1) is missing
- Switch cannot fully boot up due to a software issue (ex:Firmware upgrade or downgradewent wrong and now the switch will not boot, switch is in a reboot loop)
- Corrupted file system or CF (compact flash)
Netinstall WILL NOT FIX
hardware issues (ports not working, compact flash SCSI read/write errors, etc.).
A non-Brocade branded USB may work for this, but limited testing has been done. A Brocade-branded USB (one which was shipped with VDX switches) is preferred and have been confirmed to will work for the netinstall process.
