NetApp - ATTO FibreBridge 7500N settings
NetApp Solution · Config document · referenced from Physical design and cabling
The settings of one FC-to-SAS bridge, taken from the configuration dump the bridge produces itself. A bridge presents the disks of the SAS shelf stacks behind it to both Fibre Channel fabrics; it has no notion of aggregates, pools or owners.
| Item | Value |
|---|---|
| Device | ATTO FibreBridge 7500N, firmware 2.85 |
| Shown here | DC1-A-BNAS001, the first bridge of datacenter A at site 1 |
| Also applies to | DC1-A-BNAS002, DC1-B-BNAS001, DC1-B-BNAS002; see the differences below |
| Produced with | The command dumpconfiguration of the bridge |
| Changed through | The web interface on a management port, over HTTP, with the one local account |
| What the dump is | About 620 lines: an event log, the answers to two dozen commands, and two lists of every disk behind the bridge |
| What is shown | The settings only |
The file
# dumpconfiguration of DC1-A-BNAS001. # Settings only. Left out of the dump: the event log at its start, the # FC and SAS world wide names, the SFP and cable serial numbers, the FC # error counters, the list of 136 disks and 6 shelf enclosure devices # behind the bridge, and the IPv6 addresses, which the bridge builds from # its MAC addresses. The line counts and the "Ready." prompts that the # bridge prints around every answer are left out as well. # Lines starting with ";" are the bridge's own table headers. # --- Fibre Channel: both ports up, point-to-point, 16 Gb -------------------- FCPortList ; Port Status ;=============== 1 Up 2 Up get FCConnMode all ; Port Conn Mode ;================== 1 ptp 2 ptp get FCDataRate all ; Port Data Rate ;================== 1 16Gb 2 16Gb # --- Ethernet management ports: static addresses, no DHCP, no DNS ----------- get IPAddress all ; Port Address ;======================================================================= MP1 10.11.15.47 MP2 10.11.15.48 get IPSubnetMask all ; Port SubnetMask ;================================= MP1 255.255.255.0 MP2 255.255.255.0 get IPGateway all ; Port Gateway ;================================= MP1 10.11.15.254 MP2 10.11.15.254 get IPV6Gateway IPV6Gateway = get EthernetSpeed all ; Port Speed ;========================== MP1 1000 MP2 auto (1000) get IPDHCP all ; Port DHCP ;========================== MP1 disabled MP2 disabled get IPDNSServer Server not configured # --- SAS: connectors A, B and C carry one shelf stack each, D is off -------- # The fifth column of the original, the SAS address, is removed.

What changes on the other three bridges
| Setting | DC1-A-BNAS001 | DC1-A-BNAS002 | DC1-B-BNAS001 | DC1-B-BNAS002 |
|---|---|---|---|---|
IPAddress of MP1 | 10.11.15.47 | 10.11.15.49 | 10.11.23.47 | 10.11.23.49 |
IPAddress of MP2 | 10.11.15.48 | 10.11.15.50 | 10.11.23.48 | 10.11.23.50 |
IPGateway | 10.11.15.254 | 10.11.15.254 | 10.11.23.254 | 10.11.23.254 |
EthernetSpeed of MP1 | 1000 | 1000 | 1000 | auto (1000) |
SNMPTraps | disabled | enabled | enabled | enabled |
CoreDumpInfo | No core dump | No core dump | One core dump, dated 09/06/2017 | No core dump |
| Cable type ID of connectors A, B, C | 00, 00, 00 | 00, 00, 00 | 00, 00, 01 | 01, 00, 01 |
| Shelves behind it | 10 to 31 | 10 to 31 | 50 to 71 | 50 to 71 |
Everything else is identical on all four: both FC ports up, point-to-point at 16 Gb; SAS connectors A to C up at 12 Gb and D disabled; DHCP off; no DNS server; SNMP enabled with no trap destination; 136 disks and six shelf enclosure devices visible.
Three of the differences do not look like design. The fixed speed of MP1 on three bridges and the disabled traps on one are not explained anywhere in the notes; with no trap destination configured, the trap setting has no effect either way. The core dump on DC1-B-BNAS001 is from 2017, the year of the installation, and the notes do not mention it. The file kept for DC1-B-BNAS002 contains two dumps one after the other, with the same settings.
The event log that the dump starts with, and that is left out here, holds little more than periodic checkpoints, SCSI reservation conflicts between the controllers, and the logins to the web interface from the admin VPN.
Checked against ONTAP 9.19.1
| As built | Today |
|---|---|
| FibreBridge 7500N, firmware 2.85 | NetApp states that the 6500N and 7500N are at end of hardware support and therefore also end of software support. The successor is the 7600N, and replacing a 7500N by a 7600N in a running configuration is a documented procedure |
| Managed over Ethernet: web interface over HTTP, SNMP enabled | In-band management over the FC ports exists from ONTAP 9.5 and is the default from 9.8. NetApp recommends in-band management with IP access disabled; from ONTAP 9.5 the command securebridge switches off Telnet and the other IP services of the bridge |
ONTAP monitors the bridges by SNMP, storage bridge show | Out-of-band management of the bridges by SNMP is deprecated. The command family is system bridge since ONTAP 9.8 |
| No HTTPS, no SSH, no directory login | NetApp's bridge procedures still name only the web interface, serial, Telnet, FTP, SNMP and ICMP as services of the bridge. ATTO's own current documentation was not checked for this write-up |
| Three stacks on connectors A to C | A pair of 7500N or 7600N bridges supports up to four stacks |
The device that had to be written into the design as a constraint, because it could do neither HTTPS nor central authentication, no longer needs an address at all: with in-band management ONTAP reaches the bridge through the same FC ports the disks use.
