In order to test or effect a Disaster Recovery operation, you must restrict access to the disaster site node to prevent the node from resuming service. If you do not, you risk the possibility of data corruption.

Access to the disaster site note can be restricted in the following ways:

Turn off the power to the disaster site node Use " manual fencing " (Disconnect VI interconnects and fiber channel cables; either physically or through configuration changes on the fabric switches.)

Isolating the failed node from the surviving node could still lead to the possibility of a split brain, so this is not a correct answer.

wafl.default_security_style

Specifies the default security style assigned to a new volume. All qtrees created on the volume get this as their security style. Legal values for this option are `unix ' , `ntfs ' , or `mixed ' . The default value for this option is `unix ' , unless the node is an NTFS-only node, in which case the default is `ntfs ' .

Note: if cifs setup is run after setting wafl.default_security_style, the filer will become an NTFS security style filer.

cp_from_log_full (log full) - the current NVRAM bank is full and the system switches to the other one and starts writing this to disk. Very heavy write activity.

cp_from_cp (aka Back to Back) - filer is overloaded. The write traffic is coming in faster than it can be written and the filer is running out of NVRAM capacity in one bank before the data in the other bank can be written.

cp_from_busy is not a real cp type

cp_from_timer - 10 seconds since the last CP – it means the system is pretty idle write-wise.

The fstab file reflects the defined filesystem mount paths (including NFS mounts).

Always check network connectivity when a problem arises with a network service.

The exportfs command will display the active exports on the storage system.

In takeover mode, this network interface assumes the identity of the network interface on the partner

For the partner interface configuration to be persistent across reboots, you must include the ifconfig command in the /etc/rc file
