6. If the Memory Gateway responds properly, save the host settings using the
write mem command.
Determining IP Addresses of Internal Memory
Gateways (Both Unknown)
If both Memory Gateway IP addresses are unknown, it is necessary to power down one Memory
Gateway to properly identify which Memory Gateway is which. The following procedure powers
down mg-b.
1. Make sure mg-a is powered on and mg-b is powered off by running the following commands
on the ACM master node:
array module id mg-a enable
no array module id mg-b enable
2. Issue the following command and then verify that mg-a is drawing current (>0) and mg-b is
not:
show array module type mg detail
3. Perform a broadcast ping to 169.254.255.255 from the ACM CLI, for example:
4. Examine the output of the above command and determine the IP address that is neither
169.254.1.10 (acm-a) nor 169.254.1.11. The remaining IP address is the address for mg-a.
5. Set up the host definition for mg-a using the following commands:
no ip host mg-a <tab>
ip host mg-a <ip address>
Note: Pressing the Tab key after the first command will auto-complete the command with any
existing IP address assigned to that host. If none is present, the first command is unnecessary.
6. Verify the host definition by pinging mg-a directly using its hostname:
ping mg-a
7. Power on mg-b as follows:
violin-acma [violin: master] # ping -b -w1 169.254.255.255
