Miscellaneous troubleshooting

IBM Storage Ceph Plugin for vSphere is built with Photon OS Linux 4.0.

Pinging the virtual machine

Use this information to help with general troubleshooting, or alternatively refer to Photon OS documentation (https://vmware.github.io/photon/docs-v4/).

By default, the plug-in VM appliance does not respond to ping (ICMP) requests as it is protected by a security policy complete with firewall. This firewall drops all ping requests by default. However, you can enable ping responses:
  1. SSH into the plug-in appliance as root or connect to the VM console within the vSphere Client.
  2. Run the iptables -A OUTPUT -p icmp -j ACCEPT command.
  3. Run the iptables -A INPUT -p icmp -j ACCEPT command.

Changing network configuration

Change the network configuration on the VM appliance.
Note: The static IP configuration might need to be updated manually.
  1. Go to the vSphere instance that the virtual machine was deployed on.
  2. Log in and within the inventory go to the virtual machine.
  3. From the virtual machine Summary tab, click Launch Web Console.

    A console in a new tab launches.

  4. From the console, log in as root by using the virtual machine credentials.
  5. Edit the network config file found in: /etc/systemd/network/.

    The config file is called 10-gosc-eth0.network.

  6. Edit by using the vi or vim command vi /etc/systemd/network/10-gosc-eth0.network.
  7. Complete the network changes by using the following command: systemctl restart systemd-networkd.
  8. Verify that the virtual machine can be reached on its new network settings (for example, through SSH).
    Note: If network setting is changed, reregistration might be needed. To reregister the vSphere Plugin, by first unregistering and then registering the plug-in.
    1. Unregistering the vSphere Plugin
    2. Registering vSphere plug-in into vCenter

Create Datastore API timed out

A datastore with name NAME can be created but the datastore is not managed by IBM Storage Ceph Plugin for vSphere until the storage is refreshed from the plug-in dashboard. For more information, see Manually refreshing the storage system and vSphere objects.
