Interestingly – I’ve just been doing some prep work on the Dalsa 4k camera and their recommended drives are Ciprico also.

Yes, it seems with the very latest ATTO cards that the problem has been fixed. (Although I cannot confirm this under very rigorous testing as yet).

As for both Sonnet’s and my supplier Holdan – they couldn’t have been more on top of the problem – and it wasn’t long before we identified it as being a RAID card (ATTO) heat issue and smc fan control was implemented to alleviate the issue temporarily. The only problem was the 8hr time delay between us and the states made getting to the bottom of the issue a bit slower than normal.

Once I installed SMC fan control the problem itself almost vanished…. I have now turned off this app. on our systems and everything is stable with the very latest cards.

Adam,

I think that that is most probably good news (and your data hopefully is recoverable) and that you are looking at an enclosure / cable / or ATTO card issue…. However, the number on the ATTO config tool doesnt necessarily read down the enclosure – see this mail I have from Sonnet……

The “member number” reported in the ATTO configuration utility is not associated with a particular bay of the D800.  You have to find it the hard way, by using the command line utility (“CLI”, the 4th tab in the main ATTO configuration utility window).

You type 
rgdisplay

to display the raid group name

then
rmstatus raidgroupname

where “raidgroupname” is the name you got from the previous step. It will show which drives are degraded

blockdevidentify 6

to identify which drive is #6 for example- the LED on the front should light up, indicating which drive it was.

If the LED doesn’t work (because the drive is dead or malfunctioning for example) you find it by reverse: 

blockdevidentify 0
blockdevidentify 1
…
blockdevidentify 5
blockdevidentify 7

and drive 6 is the only one that didn’t light up.

When you remove the “degraded” drive, the status should change to “unavailable”.

Again – I hope that it helps.

Other things worth checking that we changed / checked were………

The type of drives in the array – originally I was supplied with Western Digital – and these didn’t work at all – we now have Seagate Barracudas.

Flash on the ATTO card. What date of Flash do you have on your ATTO?

Any joy with remounting the unavailable drives?

I’ll check anything else we worked on when I get into work….

Adam,

I have experienced similar problems with our Sonnet E-SATA drives (on two suites)….. I’ll cut a very long story short. Both Sonnet and our suppliers Holdan (UK) have been very pro-active in attempting to correct the issues.

The problem was traced to a Heat issue with the ATTO raid cards. As a temporary measure we ran the smc fan control utility with the fan controls cranked up fairly high to keep temperatures down. This worked and stopped the drives dropping out / becoming degraded.

https://www.macupdate.com/info.php/id/23049 for the smc fan control

We recently received replacement ATTO cards which are ‘latest – heat tested versions’. Two weeks ago we switched off the fan control and although our workload has been light – so far, so good.

When a single drive became degraded – I took it out of the enclosure and then re-seated it, then rebuilt the RAID. (RAID 5)

We did however have one suite with both degraded and one unavailable – which caused me to sweat a little. Upon re-seating all the drives in the bay – the unavailable drive re-appeared and then I followed the same procedure to rebuild the array.

I hope that this helps in some way. However if those drives don’t come back then the outlook for that data is rather dire I’m afraid.

As a matter of interest – what kind of mac are you running?

[Mark Rodway]

I don’t understand what you mean by flex files – But in my experience – the re-telecined footage onto HD ‘should’ have the same Timecode as the SD material and therefore you follow the usual onlining procedure….

[Mark Rodway]

Thank you both for your thoughts on the matter……………

I’ve trawled the net looking for a solution (cross platform) – and drawn a blank also….. Something whereby everybody who opened the QT would have to type a p/word…..

Thanks again anyhow.

regards,

Mark

I had the issue when working at 1080 and in 10 bit colour sspace – it cleared when I was working in 8 bit.

I had the same issue…………

I purchased an ATI 1900XT card (512mb) – problem solved.

Unsure if this is compatible with your brand new MAC….???????

I’ve just completed a project at 1080 ProRes HQ and the data rate for the files was just 22mb/sec – so you should have very few problems with throughput…..

The only issues I came across were FCP’s dislike for dissolving from one shot to another when speed FX were included in the mix – I had to render out the Speed FX first and bring it back in…

ProResHQ really is just another codec – albeit – a slightly flaky one at this time….. But not that flaky – honestly.
