Symptom
You upgraded to OS X 10.7.4, you're in 32-bit kernel mode, and now have trouble mounting/unmounting SANmp volumes with v.4.0.

Resolution
Switch to 64-bit kernel mode if possible. If you cannot switch to 64-bit kernel mode, continue using OS X 10.7.3 and watch this KB article for updates.]]> Thu, 17 May 2012 15:28:01 +0000 http://www.snsforums.com/index.php?showtopic=557 http://www.snsforums.com/index.php?showtopic=554
We found SANmp volumes to be very stable, but have still lost some volumes to to hardware malfunction (one UPS failed in a power failure - leading to one 3TB volume lost) and also to user mistakes (leaving the SAN plugged in while installing a fresh Mac OS)...

Disk failures and controller failures generally don't cause data loss - touch wood. A serious controller failure writing junk to disk can also cause big problems, but we have not had such a problem in the 7 years on SANmp.

We have always been able to back up critical volumes to other volumes on the SAN, but our space requirements grew exponentially since clients shot on camera cards and want to keep footage forever...

We feel DLT tape is expensive and slow. If we lose a whole volume, it will take days to restore from tape. Backing up to firewire disks work ok but they become unreliable when the firewire chains get too long... We resorted to archiving to 2TB WD green disks (always two copies...) before deleting stuff, but keeping a daily backup that way is totally impractical.

What do you use for backing up critical volumes? Hardware and software? Would you recommend it?

Thanks

Im a Sales engineer with Nimble Storage - We manufacture a high performance iSCSI SAN appliance. I'm currently using GlobalSAN with our device for several uses - all in the course of product demos from my MacBook. Our device has 5 GbE ports for iSCSI, plus and additional iSCSI discovery address that "Floats" across ports within that subnet.. Best practice is that all of these ports remain in one subnet, and the initiator arbitrate load balancing via multipathing - With VMware or Linux, we will toggle to "Round Robin" against 2 or more vnics, and with Microsoft initiator we can actually get the preferred "Least Queue Depth" In all cases, the initiator arbitrates the multipathing connecttion - in the case of Linux, via the devmapper package.

The Multipathing model you all are currently using (multiple subnets) to distribute the load out isn't really workable in most production shops, and is completely unworkable with a SAN appliance such as ours or EqualLogic. Multipathing seems to be mostly forgotten in the (small) Mac iSCSI initiator world - and it's really the key to not just high performance, but even high availability. Glad you all are trying, but I'd really love to have more.


Any roadmap plans to add robustness to this stack by offering at least round-robin connection arbitration within the same subnet?]]> Thu, 26 Apr 2012 18:09:55 +0000 http://www.snsforums.com/index.php?showtopic=553 http://www.snsforums.com/index.php?showtopic=552
"The change you wanted was rejected.

Maybe you tried to change something you didn't have access to."

Turns out cookies are required. Maybe the page should say as much when it fails.

Half of the drives in my promise media raid enclosure are showing a red light above a consistent green light. I'm not sure what all of this could mean but I'm hoping that I have not lost any data and that the system may have a safety or reboot mode. I really need assistance with this ASAP.

Thanks,

I'll call them machine 1 and machine 2. Both machines have trial versions of SANmp client, SANmp admin, and globalSAN iSCSI Initiator and Xtarget installed on them.

My end goal is to have both computers run FCPX and access the same HD drive over the network at the same time.

Machine 1 has a 2TB firewire800 drive connected to it. The drive has been converted using the SANmp software and then I was able to locally mount it to my desktop. It appears as a sanMP RW drive.
On machine 2 I open up SANmp client and log in...I can't seen my 2TB firewire800 drive connected over the network to machine 1. How can I connect both computers?

I assume that I need to set up a portal in Initiator on machine 2 to connect to machine 1...though when I try to connect I get a connection error "Code E3FF83BD. The globalSAN initiator is not activated. Click the License button to activate." When I go under the Xtarget License tab it says "Trial mode: 11 days left."
Is there anyway to test this software on both computers without purchasing it?

Question 2: Is it possible to make FCPX recognize a SANmp drive as a SAN location?
Basically in FCPX I would like to click File > Add SAN location and add a shared SANmp drive. FCPX currently won't let me at my SANmp RW drive mounted locally on my desktop.]]> Tue, 27 Mar 2012 20:06:20 +0000 http://www.snsforums.com/index.php?showtopic=550 http://www.snsforums.com/index.php?showtopic=549
i have followed the advice:
restarted -> same thing.
uninstalled -> restarted -> reinstalled -> restarted -> same thing, same error.

any idea where i can look for clues?

thanks,

Is there any docs on using XSAN over iSCSI with globalSan initiator?

I am going to tell you what I do have, what I want to do, and you tell me what do I need
We work on Mac OS Lion, Mac Pros and iMacs. We have Final Cut X. We have Synology Diskstation DS+1512 (I believe RAID5, I am not tech sorry
We need to store Final Cut events and projects on the Diskstation. When working on Final Cut X with USB disk is horribly slow.
We created a iSCSI target and LUN (file system).
We also have Parallels virtual machine on the SSD, the idea would be to move this virtual machine to the iSCSI volume. I am not sure if performance will suffer considerably. Anyway we are not active users of Windows 7, but we need it for certain programs.
I am not sure if by moving the file onto the iSCSI volume I will be able to open it from different machines (obviously not concurrent use)

Which software do you suggest? Can we create a iSCSI volume for example 1TB with 1 partition to accomplish all this?
