I see   no risk to do this command on a switch, because we use it often

in   customer environments without any problems| The command reboots the

partitions   in the CP, this means the CP is still working while one of

the 2   partitions is rebooted.

Hello   Roger,

here   the answers from Brocade:

AAA:   Why did the hareboot not work correctly?

Unknown.   If the switch is going through a state change during the reboot

a   cold recovery is required as the state of the connected devices cannot

be   guaranteed. If the switch cannot propagate the proper state to

switches   during the hareboot, a cold recovery will be required.

BBB:   Is there anything to do for preventing this issue?

No.   Avoiding periods of high traffic and, of course fabric instability

lessen   the chances of failure.

CCC:   Is the hareboot command supported?

It is   available, but not customer facing and not documented in our

manuals. It   is a part of the firmwaredownload routine and there are

times   that we specify its use to a customer. Does this mean that we

guarantee   that it will work 100% of the time, in every situation? The

answer   is no. There are occasions under which the hareboot command

cannot   execute (see AAA )above and a cold reboot is required.
