Note: RLM is required.
If filer is in a clustered state, go to one of the filers and issue the command to check the current status:
>cf hw_assist status
Local Node(netapp1) Status:
Inactive: filera not monitoring alerts from partner(filerb)
Fail to bind UDP socket to port 4444 IP address 10.61.69.125
To configure hw_assist, you will need to determine which interface you will use for the configuration. Interface e0m is preferred when setting up hw_assist to separate traffic, but e0a is the default if e0m is not configured and online. If you will be using e0a, you will need to make sure name resolution is working. No additional configuration is needed to use e0m.
- Determine the interface to use:
filera> ifconfig -a
e0M: flags=948043 mtu 1500
inet 10.61.69.122 netmask 0xffffff00 broadcast 10.61.69.255
partner e0M (not in use)
ether 00:a0:98:0c:3d:a6 (auto-100tx-fd-up) flowcontrol full
e0a: flags=948043 mtu 1500
inet 10.61.69.120 netmask 0xffffff00 broadcast 10.61.69.255
ether 00:a0:98:0c:3d:a4 (auto-1000t-fd-up) flowcontrol full
filerb> ifconfig -a
e0M: flags=948043 mtu 1500
inet 10.61.69.127 netmask 0xffffff00 broadcast 10.61.69.255
partner e0M (not in use)
ether 00:a0:98:0c:40:3e (auto-100tx-fd-up) flowcontrol full
e0a: flags=108042 mtu 1500
inet 10.61.69.125 netmask 0xffffff00 broadcast 10.61.69.255
ether 02:a0:98:0c:40:3e (auto-1000t-fd-up) flowcontrol full
- Turn on hw_assist on for both heads (if needed):
> options cf.hw_assist.enable on
- Set the partner address for hw_assist:
filera> options cf.hw_assist.partner.address 10.61.69.127
Validating the new hw-assist configuration. Please wait...
filera>
filerb> options cf.hw_assist.partner.address 10.61.69.122
Validating the new hw-assist configuration. Please wait...
filerb>
- Set the hw_assist port for both heads (if needed):
> options cf.hw_assist.partner.port 4444
Validating the new hw-assist configuration. Please wait...
>
- Check hw_assist status for both heads (may take a few minutes):
filera> cf hw_assist status
Local Node(filera) Status:
Active: filera monitoring alerts from partner(filerb)
port 4444 IP address 10.61.69.122
Partner Node(filerb) Status:
Active: filerb monitoring alerts from partner(filera)
port 4444 IP address 10.61.69.127
filerb> cf hw_assist status
Local Node(filerb) Status:
Active: filerb monitoring alerts from partner(filera)
port 4444 IP address 10.61.69.127
Partner Node(filera) Status:
Active: filera monitoring alerts from partner(filerb)
port 4444 IP address 10.61.69.122
The status will not change to monitoring alerts from the partner until the next keep alive ping has been received. Once the ping has been received, the status will change to active for both the local and partner node.
As an alternative, test the configuration with the test command:
> cf hw_assist test
cf hw_assist: test command successful
