I've a problem with Brocade Swtiches 8 GB 10 internal to IBM Bladecenter H
which is connected to Storage IBM V7000 .
There seem to be errors in link speed negotitation upon rebooting the storage.
We've set parameter for port connecting to storage to fillword=3
however the storage show link speed change (from 8 GB to 4 GB)
Also internal blades experiment problems connecting to storage
(they have Qlogic QMI2582 CIOV 8 Gb mezzanine card)
with "Invalid Trasmitted Word" error in ports of blade connected.
We would like to try to downgrade firmware on such switches
from rel. 6.4.2b (which is the latest)
to previous 6.2.2b ,
which doesn't have fillword setting to specify.
It is possible to do such operation ?
Any other suggestion ?

portcfgfillword other than " 3 " for Storage V7000
will cause port to be disabled with errors,
so this is no option.
For internal blades,
suggested from IBM,
(we have Qlogic HBA)
is fillword = 1 ,
maybe worth try changing to 0 ?

Can you confirm the Blade Switch is:
switchshow command output
SwitchType 73.x ?
if yes, this is Brocade Blade Switch 5470 and NOT Supported by FOS 6.2.x
with other word, you cannot downgrade to 6.2

zoning: ON (ConfSWFC1)
So no possibility to downgrade to 6.2.x ?
I've found link in IBM support
for FOS 6.2.0_bc3
Maybe possible with this version ?

you ask in the threads to Downgrade to 6.2.2b also GA = General Available.
--->>>Downgrade FOS from 6.4.2b to 6.2.2b
6.2.x GA Releases, AFAIK not supported the Blade 5470
6.2.0_bc"x" release is OEM Specific Release in such case is "bc" for IBM, e.g. DEL for DELL Computers, HT For Hitachi etc.
