Dell T630 Dell PERC H730P and missing disks

Hello,

I have a Dell T630 which HDDs keeps going off, bays for those HDDs are missing too, not showing in BIOS settings under PERC. Controller type is PERC H730P 12Gb PCIe 3.0 x8 2x SFF-8643 Raid Controller 2GB Cache.

There is one virtual disk RAID 5 with 8x2,5" 1,8 TB 10k SAS 12G Raid Enterprise Storage 24/7 HDD. Two "rows" of 8 similar disks per row and the upper 8 is in use, and the lower 8 disks just waiting for configuration. But.

0) Initially server was ok with HDDs.

1) HDD on bay 0:0:7 broke first on the very first day of production use, was replaced succesfully and then this HDD broke again in 2 months. Had to do "foreign" configuration reset fist for the replacement HDD, but after that worked.

2) New replaced disk broke in ~1 month, in the slot 0:0:7. All leds were off in this particular disk.

3) Now a HDD in 0:1:15 had died, leds off. Put a new quarantee replacement HDD (brand new) in 0:0:7, it was dead on arrival. All leds off in these two disks.

4) Swap a working HDD from 0:1:14 --> 0:0:7 and worked fine in here. And vice versa, now 0:1:14 bay with dead disk is dead, all leds off in this disk.

5) Also tried to swap 0:1:14 <-> 0:1:15 but no difference. Leds are off in these bays, where dead HDDs are in. They (bays or disks) don't show up in BIOS, under PERC H730 config.

Every time I have switched off the server before operations, grounding myself, so no mistreatment of HDDs or server. It is hard to believe that this server eats HDDs every 2 months. Any ideas? Thank you in advance. iDRAC is version 8.

MattiP,

 

I would start with powering down the server, remove the power cables, hold the power button for 20 seconds  (drains flea power). After that then reseat the raid chain, basically the raid controller, the backplane cables, the backplane, and the drives. I would also highly recommend that you update the server on BIOS, iDrac, H730P, and the drives (if available).

 

Let me know what you see.

Hello Chris,

Thank you for your advices, I made hours of work on this and mainly because of my own stupidity. Some of the disks were initially broken, but some of the new ones weren't. This is embarassing, but I put SAS disk on SATA's place in a tray caddy (screw holes match perfectly) and thus the SAS disk didn't touch the backplane at all. So, need to pay attention that how SAS/SATA disks should be mounted on the tray caddies..

But after HDDs were lid up ok, the whole PERC 730 was missing from iDRAC. For this part, plugging AC cables, pressing and holding power button and hardbooting couple of times brought everything got back again. And luckily no need to rebuild any RAID.

Thank you!
