NAS Help

[MatthewL]

I have a couple of QNAP NAS which I currently use for shared folder storage and does the job but I want one setup using iSCSI so I can set it up as volume on my server without been shared if you get me.

 

I have 3 options when creating they are:

1. iSCSI Target with a mapped LUN

2. iSCSI Target only

3. iSCSI LUN only

 

Now I presume I will go with number 1. It then asks for a target name and alias, what does this mean as such, I know I can put in what I want but what does this relate to?

 

It then asks for CRC/checsum on data and header digest, do I turn this on?

 

CHAP authentication presume will be no.

 

When I go through the wizard I then create an iSCSI LUN, I presume this is the storage (i.e. 25gb) as it asks me capacity but again with name anything in particular.

 

I haven't done done this for such a long time I wasn't sure if things need to be named a certain way or what, some help would be appreciated.

 

Thanks

Its been a while but off the top of my head - for Target Name I put in the Server that I was going to connect it to. For Alias I just typed the same. Don't think I did the CRC/Checksum as it was optional. Didn't do CHAP. Did instant allocation. Gave the LUN a name like "SVR1Conn" finish.

 

I then went to the server and used the MS ISCSI initiator to connect to the LUN.

 

I think that was it.

Hey, I'm not all that familiar which iscsi setup. I did recently re-setup our dlink nas as some muppet have only provisioned 2tb from a 25tb array.

 

I think the LUN and/or name is just the volume identifiers on the NAS, which is what your'll use on iscsi Initiator (pursuming your on windows) to identify which volume your connecting to, we didn't use CHAP as NAS is only connected to one machine (a total waste i know), if its available from your internal LAN you might want to think about access rights. CRC again that will depend on what kinda data is on there and how important its integrity is.

 

Hope this has helped, iscsi configuration seems to be one of those things you do every 5+ years and needs words of encouragement before making potential bad configuration decisions you have to live with for the next 5+ years.

Thanks for that, it was roughly what I expected.

 

It's only on my home LAN so not too much of a worry but this NAS has a bit where you can restrict what can connect to it for iSCSI.
