ATTO HBA LUN ISSUE - AGAIN, this time with 10.9??? RESOLVED!

Forums: 

I used to have issues with ATTO 41/42ES HBAs seeing all the LUNs on our XSAN system (Qlogic 5600/Infortrend RAIDS). Replacing the problem client PCI card with an Apple 4Gb card eliminated the problem.

Since updating the XSAN to Lion 10.7.4/10.7.5, and using the latest available ATTO drivers/flash files for the 41/42ES - the problems 'had' disappeared.

Unfortunately, while rumming some pre-upgrade tests using a metadata controller on Mavericks 10.9.1, it appears the problem has reoccured. Its a real issue now as I have many connected clients running the ATTO cards, and updating the MDC OS may or may not make them stop seeing the various XSAN volumes.

I've tried flashing the ATTO firmware etc, but a test client machine I have here happily running on an ATTO 41ES and Lion 10.7.5 to our existing 10.7 MDC, when connected to the test 10.9 XSAN will not see some LUNS on either 10.7 or 10.9. Swap the HBA for an Apple, and hey presto - there they are. Grrrr!

Has anyone come across this issue - or better still got a fix (that does not involve buying Apple cards!) ?

Thanks

Open Directory Replica on a MDC - Incorrect Search Policy

Forums: 

Im having an issue I hope someone can enlighten me on. 

I have an xsan environment with 2 metadata controllers. MDC1 is just a the master controller. MDC 2 is also a AFP re-share and is an open directory master. 

All clients and MDC’s are bound to MDC2 open directory master. 

When MDC2 needs to be rebooted all clients loose ACL’s to the xsan because the OD is offline. 

I made the MDC1 an open directory replica and that functions as expected. Unfortunately now in xsan admin MDC1 now says “Incorrect Search Policy”  because it is now bond to itself and not MDC2. 

How can I have both? Can a MDC not be a OD Replica?

Lion and Mavericks

I made a snap decision to upgrade a workstaion to 10.9 completely forgetting that XSAN would be unhappy as our MDC is on 10.7.  

Has anyone done either of the following?

Install an older version of the XSAN client on 10.9?  or

Forced an upgrade to 10.9 on an Xserve that isn't supported?

Any other creativesolutions for getting around this predicament would be great.  (I could roll the workstation back to 10.7 but I'm saving that as the worst case scenario)

Thanks.

Mavericks OD Replica problems on upgrade

Upgrading ML Xsan MDCs to Mavericks - same issue on every system we build in the lab and several clients - OpenDirectory Replica does not survive. Attempts to re-create the OD replica fail with this message:

2013-12-23 07:58:15 +0000 NSMutableDictionary *_getRootDSE(const char *): rootDSE not found
2013-12-23 07:58:15 +0000 Error: Unable to determine the master's software version.

And yes I've tried the SSH fixes. They don't seem to do anything.

Mac Pro 2013 Processor Upgrade Confirmed by OWC

Confirmation came from OWC today, you can indeed swap processors with the new Mac Pro. This is huge once these prices start falling down the road. They used an Intel E5–2667, this is interesting as upgrade options will be very interesting when these chips prices drop in a few years.

Mac Pro 2013 Article Roundup

The new Mac Pro has already seen a ton of reviews and information. Here is a collection of a few great links.

Probably the best technical review from AnandTech. For a less geeky review, there is a good general review from Macworld, which helps explain why the 8 core chip is probably the best bet for most users. If you want to dive deeper into the different CPU configuration options and what they mean, check out this post from iOS Dev Marco Arment. Understanding the Turbo feature on these new chips is really important. There have been some reviews critical of the new machine, Dave Girard at Arstechnica has some interesting points.

Finally, for those of you interested in future upgrade/exapandibility of the Mac Pro. Check out this great teardown from iFixIt.

Using the Mac Pro (Late 2013) on its side

From Apple KB http://support.apple.com/kb/HT6099

Although the Mac Pro (Late 2013) is designed to operate in an upright position, you can also use it on its side.

The Mac Pro (2013) has a fan system capable of cooling the computer in a vertical or horizontal orientation as long as you follow these guidelines.

  • Provide enough space at each end of the computer for unrestricted airflow into the base and out the exhaust at the top. Make sure that the air intake and exhaust ports are not covered.
  • When using multiple Mac Pro (Late 2013) computers, do not direct the exhaust at the top of one Mac Pro towards the intake of another system. Place the computers side by side with a gap of at least several inches between them.
  • When on its side, secure the Mac Pro (Late 2013) to be sure that it doesn't roll. Place the computer on a protective surface that will not scratch or damage the enclosure. Note: The Apple Limited Warranty does not cover cosmetic damage to the enclosure.
  • Orient the computer so that the Input/Output (I/O) panel remains accessible during use.
