It’s a couple of years since the post - ATTO
Bridge Configuration Notes (for MetroCluster) - and now time for an update!
Most of the information here comes from the ONTAP 9 Documentation Center
and these articles:
[1] In-band management of the FC-to-SAS bridges
[2] Installing FC-to-SAS bridges and SAS disk shelves
> Preparing for the installation
[3] Enabling IP port access on the FibreBridge 7600N
bridge if necessary
[4] Configuring the FC-to-SAS bridges
[5] Updating firmware on FibreBridge 7600N or 7500N
bridges on configurations running ONTAP 9.4 and later
Notes
[1] “Beginning with ONTAP 9.5 with FibreBridge 7500N
or 7600N bridges, in-band management of the bridges is supported as an
alternative to IP management of the bridges.
“Physical access to the bridge via the bridge Ethernet
ports is not required
“Using
in-band management with IP access disabled is recommended to improve security...”
Q: Does the ATTO 7600N
have a WebUI?
A: Yes it does, but you have to enable it via a serial
connection to the ATTO 7600N using [3] -
set closeport
none
saveconfiguration
Note 1: Of course, enabling the WebUI is not the
recommended configuration (see above).
Note 2: You should disable the services you don’t
require using -
set closeport service
saveconfiguration
- where service is
expressnav/ftp/icmp/quicknav/snmp/telnet. And check using:
get closeport
Q: How to configure the
FC-to-SAS bridges using in-band management [4]?
A: See below:
(0) For completeness, these first 5 commands are only
required if you want to configure IP access:
set
ipaddress mp1 ip-address
set
ipsubnetmask mp1 subnet-mask
set
ipgateway mp1 x.x.x.x
set ipdhcp
mp1 disabled
set
ethernetspeed mp1 1000
(1) Configure the bridgename:
set bridgename bridgename
(2) Running ONTAP 9.4 or earlier, enable SNMP
on the bridge:
set SNMP
enabled
(3) Configure the data rate/speed of the bridge FC ports:
set FCDataRate port-number port-speed
(4) For FibreBridge 7500N or 6500N (not 7600N), set
connection mode to PTP:
set
FCConnMode port-number ptp
(5) Configuring a 7600N or 7500N and not using the FC2
port, disable it:
FCPortDisable
2
(6) Configuring a 7600N or 7500N, disable unused SAS
ports, for example:
SASPortDisable c
SASPortDisable d
(7) Save the bridge configuration:
SaveConfiguration
FirmwareRestart
(8) ONTAP 9.5 or later and configuring for in-band
management. Secure access to the bridge:
SecureBridge
(9) Check firmware version of the FibreBridge and
update if required:
flashimages
(10) To configure FC-to-SAS bridges for health
monitoring in the clustershell::>
storage bridge add -address 0.0.0.0
-managed-by in-band -name bridge-name
Q: How to update the
firmware of an ATTO 7600N or 7500N bridge using in-band management in ONTAP 9.5+
[5]?
A: First download the firmware from NetApp -
- and then run these commands from the Clustershell::>
set -privilege advanced
storage bridge firmware update -name
bridge-name -url URL-of-firmware-package
set -privilege admin
job show -name Storage bridge firmware
update
-- Takes approximately 10 minutes --
storage bridge run-cli -name bridge-name
-command FlashImages
To restart the bridge (not required from version 2.95):
storage bridge
run-cli -name bridge-name -command FirmwareRestart
Finally verify firmware update::>
node run -node nodename -command
sysconfig
storage bridge show -fields
fw-version,symbolic-name

7600N or 7500N bridges:
