Re: [Networker] Writing to LAN when SAN not available

Hi Caroline

The key to this is the client resource's 'Storage nodes' field.  This field
determines which system will write the data to the output device (tape,
disk, etc.).  If the client's own hostname is entered in this field, then
the client is, therefore, a storage node, and write its data to whatever
output devices it has been configured to use.  If another systems's hostname
is entered, then the client will ALWAYS send its data via IP to that other
system (which is the storage node in this case).

Also, the 'Storage nodes' field is an ordered list.  NetWorker will attempt
to use the first storage node in the list; if it can't, then it will attempt
to use the second storage node in the list, and so on.  The "can't use" is
defined by being unable to mount an appropriate volume within the selected
devices' "Save Mount Timeout" attribute value.

So, in our case, if you have a system that usually backups up via the SAN
but the fallback is to back up over the LAN, you would specify, in the
'Storage nodes' field for that system:
[that system's name] - for backing itself up over the SAN
[other storage node] - for backup up the client over the LAN

in that order.

Hope this helps!

Subject: [Networker] Writing to LAN when SAN not available


Hi All,
 
We are doing some SAN backups, if for some reason the devices on the
SAN aren't available, what criteria does Networker use to decide when to
write back to the LAN. 
We are using Networker V6.1.3.
 
Any input is appreciated, thanks,
Caroline
