Network IP Route.

Solution

Please note that changing the library IP will require the library to be in an offline status to all the hosts. This process will also require the library control software to rebuild its configuration database.


1. Login to the library

    With the Dual TCP feature, if only one connection to the library is being used, SSH to the second port (i.e., 2A). Port 2A, if not used for HLI communication with the host,
    can be used as a service port.

    If the Dual TCP feature is enabled, changing both 2B and 2A IP addresses (or hostnames) will require connecting a laptop to the library's service port.

    Login to the library as user "admin", "service" or "remote" to be able to run the appropriate CLI 'network' commands.


2. Display the configured network settings and save these information for later use.
    On the CLI prompt, run these commands:
  
    When Dual-TCP feature is enabled:
    SL8500> network ip address show

    For a single port configuration:
    SL8500> network print

    If static routes, default routes and policy routes are currently defined, also run the following to obtain currently defined values:
    SL8500> network ip route show
    SL8500> network ip policy status
    SL8500> network ip policy route show dev 2B
    SL8500> network ip policy route show dev 2A


3. Bring down the communication link to the host
    Please note that the 2B (and 2A, if Dual-TCP feature is enabled) port communication with the library control software should have been stopped at this point.
    SL8500> network ip link set dev 2B down
    SL8500> network ip link set dev 2A down (if not SSH'd on this port)


4. Change the IP addresses
    SL8500> network ip address del <Old Ip address>/<NM> dev 2B
    SL8500> network ip address del <Old Ip address>/<NM> dev 2A (if Dual-TCP is enabled)
    SL8500> network ip address add <New Ip address>/<NM> dev 2B
    SL8500> network ip address add <New Ip address>/<NM> dev 2A (if Dual-TCP is enabled)

    Note:  If a default router has to be set as a result of the IP address change, setup the default router using this command:
    SL8500> network ip route add default via <router IP address> 

    To verify:
    SL8500> network ip route show


5. Bring both ports back up.
    SL8500> network ip link set dev 2A up
    SL8500> network ip link set dev 2B up


6. Verify currently defined network attributes:
    When Dual-TCP feature is enabled:
    SL8500> network ip address show

    For a single port configuration:
    SL8500> network print

    If static routes and policy routes are currently defined, also run the following:
    SL8500> network ip route show
    SL8500> network ip policy status
    SL8500> network ip policy route show dev 2B
    SL8500> network ip policy route show dev 2A

    Note: If policy routes are configured, run these commands to enable policies:
    SL8500> network ip policy enable dev 2A (If Dual-TCP is enabled)
    SL8500> network ip policy enable dev 2B

    Then, verify that the policy routes have ben enabled:
    SL8500> network ip policy status


7. Verify if the host server is able to communicate to the library.


8. Once the host server is able to communicate to the library with the new IP address, reconfigure the library control application to rebuild the configuration.
    Please refer to these documents to assist with reconfiguring the ACSLS database:
