It shouldn't be that complicated of a system. Positive, Negative/Ground, Temperature wire, but what are the other 2. There is Red,Black,White, Green, Yellow. I think yellow is the temp sense, but white and green? Maybe one keeps track of how many charge cycles it's been through. It does show a cycle count of 14.

Oh and the last patrol read completed 24 hours prior to running those benchmarks.
43mAh (ie nothing) tells me your battery is dead - LI-Ion batteries do not take deep discharges well, and often cannot be recharged as a result.

This doesn't explain why the problem happened though - it could be entirely down to a bad battery, or the PERC could have shorted the battery and fully discharged it which killed it...

Well in MSM it is drive 2 so I don't think it is on the other sas controller. I will swap it with a drive on the other known good ports though. That would point to a bad card if true though.

Would that imply that the positive red wire was grounded. Since black is ground and I've seen that red is grounded to the pci bracket isn't that the same?

Hello,

I just received today my PERC 6/i bought on Ebay (80$ french customs duty ... what a surprise...).

I hadn't yet received the SAS cables i ordered, but i'm already faced to two "problems" :

* Did someone manage to find a specific PCI bracket that could be used with this card (someone use perc card without bracket ??) ?

I saw that thideras managed to make a DIY pci bracket for his card :

http://www.overclockers.com/forums/s...&postcount=493

* By the way, in the previous post, i noticed that thideras also is faced to the same question : how to mount the battery (i'll try to find a dell server with one mounted to see how it's done) ?

Thank you very much for your answers,

Sincerely,
bubulle_b0x

Update : hadn't noticed that on one of the links it refers to "network cards standards".

Tomorrow, i'll search on a big box filled of old nic cards !

Related to PCI bracket i found this post :

http://www.hardforum.com/showthread.php?t=1459008

It links to this :

http://www.keyelco.com/products/specs/spec167.asp

http://se.mouser.com/Search/ProductD...ualkey534-9203

Do someone know how to find this standard PCI "9203" reference at lowest price (on Ebay, etc...) ? (On the site : 30$ delivery to France )

Or perhaps some hardware already has this bracket type ? Any reference ?

(Was searching on a lot of vga cards, etc... )

If you two are resourceful, you can get prototype PCI brackets from companies that are nice. I got 2 sent to me for free that fit perfectly and have the 2 screw tabs. I don't want to say the company because it'd be mean if they all of a sudden got 100's of requests, but, if any of you went to school you'll be familiar with the process.

Borito is sending a bbu/cable that is known working for me to test with, hopefully that gets me to the bottom of the bbu not recharging issue.

As far that drive that reported 240 errors, it's now up to 480 errors. Is there an easy way to know which cable is connected to the drive without trial and error? If I DC it and then Reconnect I really shouldn't need a full 2hr rebuild right? Anyway, I'll unplug this drive and try another port, if I get more errors. I have a feeling the major spikes down to 5MB/s all over the place are something to do with the drive not working right.



Question: Can you have non member drives on the same controller that you are running raid with the PERC 6/i? Would it be beneficial to put my OCZ Vertex SSD 120GB on the controller with 5 other raid 5 drives?

Borito is the man, he is a stellar chap.

In your MSM, it should be giving you some information on which drive (specifically the address) that has the errors, right? If you know that, you should be able to track the cable down.

And yes, you create a RAID0 virtual disk and add the single drive to it to use drives in single disk mode. You are of greater benefit leaving it on your onboard controller, though, because cache burst speed and access time is far better on the QPI-Linked onboard SATA ports. You wont see much of a difference in sequential read or write from a single disk on the PERC over onboard.

Well it says the addresses are 0x122100000Y000000 where Y is from 0 to 4 which correspond to port 0-4. So yeah, it should be port 1 according to that. I should label these cables with freezer tape or something...

Lol so I made a big mistake. I unplugged disk 4 which was an ok disk, then plugged it back in, it started rebuilding and i figured i could stop the rebuild but let it go anyway. Then the bad drive started throwing errors again, all of which were unrecoverable because of the other drive being rebuilt. I then cancelled the rebuild and ran a consistency check. I'm getting about 6-7 "uncorrectable multiple medium errors" so far, half way through. Does this mean I'm going to run a movie or file and find out it's corrupt now (whichever file that bad sector will infect) ?
