    Problems with a Dell TL4000 SAS tape library + LTO drives

    It does? I didn't notice, but I took a video of it in action with the cover off, I'll have another look. Good if you have a full-size rack - mine is 18U and even that's bigger than I intended, I wanted 12U! I really need to reorganise mine and use more of the back face of the rack... Agreed on...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Ah, on closer inspection I can see the 'Made in Germany' on the label of this drive that I thought was IBM: HP MSL LTO5 Ultrium Tape Drive BL540B/695111-001 | eBay It is a Superloader 3, and I actually found that exact article when I was looking for ways to get the magazines out without...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Not saying you didn't! I mean the IBM label on the top of the drive itself. See the picture in this post. The white-label drives are out of the autoloader, while the black-label one is standalone. The label on the back of the sled near the data connector is consistently black in my drives, and...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    So, to share a few more things I've discovered recently through experimenting with my hardware: First, the robot error was due to the shelf above it (supporting one of my servers) being bent down far enough that the edge contacted the top shell roughly in the centre. The clearance must be...

    Internal and external SAS on the same card

    Yeah, the card is stable in normal use despite the alarmingly high temperatures. I'd prefer one that ran cooler if possible though, due to the cramped case.

    Internal and external SAS on the same card

    Hey folks, Reviving an older thread, but I'm running into issues. I bought the ASR-78165 and it works okay, aside from running quite seriously hot - I have an 80mm thin fan sitting on top but even then it's running around 80'C (though Arcconf says this is Normal...). The problem is that...

    Adaptec ASR-78165 SAS controller - external tape libraries have single LUN and cause lockup in HBA mode (Linux)

    Hi folks, I've had this issue now with two different types of tape library so I know it's the card. When connecting to a multi-LUN device (i.e. a tape library with robot), only the tape drive shows as a SCSI device. The robot is not visible. After a while, the entire card locks up and crashes...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    That's correct, the SAS drives in my NAS are in a 6-disk Z2. The ASR-78615 is in HBA mode. I rebooted the NAS for kernel upgrades earlier today and I couldn't see anything in the RAID card config to do with multi-LUNs. I'll try it. That machine is enormously heavy so pulling it out of the rack...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    I only get the 'Drive logged out' message with the LTO-5 drive. The drives I got with the library tend to allow it to fully initialise. However, I'm now getting errors on the robot positioning...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    The exact model of the SAS card is an Adaptec ASR-78615. Unfortunately I don't really have the option of a different card because the NAS is an ITX one, so I only have the single expansion slot. Appreciate the offer but I'm not even in the same country, I'm in the UK!

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Well, further issues. This TL4000 keeps crashing the SAS card on my NAS. Initially I thought it was overheating - the fan had failed - but now I've replaced the fan, it still causes IO errors and locks up my zpool with minor kernel panics. I don't think this thing is ever going to work for me.

    Problems with a Dell TL4000 SAS tape library + LTO drives

    These are the drives I got with it, plus mine: The black label one is the LTO-5 drive out of my PV114. The drive that isn't in a caddy is a known broken LTO-4. I've now put the middle drive, the LTO-4, in the library. Let's see what happens.

    Problems with a Dell TL4000 SAS tape library + LTO drives

    I upgraded the library controller firmware to latest, yes. I could try again, I guess. I'm about to try putting the LTO-4 drive in and see what happens.

    Problems with a Dell TL4000 SAS tape library + LTO drives

    So the LTO-5 drive registers as IBM ULTRIUM-HH5 H971 I updated the firmware myself using the Dell update packages. Took a while to figure out which one had the LTO-5 firmware in it but it updated to this revision successfully. This shows in dmesg and in ITDT. There's still no LUN...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Wow, there's a lot of info here, thank you very much for your post Terry! I moved the LTO-5 drive to the bottom slot. On booting the library up, it still showed an LTO-3 drive there and error 'FB 01'. I just rebooted it and the library is once again scanning all slots. Wonder if it'll make any...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Unless it's not the sled, but the slot, then. I may have to look more closely at what it thinks is in the slot and what was last in it...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    The library does have some hot-swap capability AFAICT, it will recognise when a sled is removed and reinstalled, and will attempt to initialise the drive once plugged in fully. However, I have completely cold-booted the library and the problem persists. It only identifies what was last in the...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    As far as I can tell, mtx is specific to the robot - it allows for tape loading and movement operations. I'm not 100% sure but I don't think it has commands for the drive once the tape has been loaded. So you have to use mt and mtx together. But in any case, yes, on the machine I had this...

    Problems with a Dell TL4000 SAS tape library + LTO drives

    Yep, I had no idea I'd encounter quite so many issues. I mean, we use much bigger tape libraries at work (>100PB onsite) and a team member maintains it, but I'd hoped something smaller would not generate as many curses! The library boots slowly even though I have only a small number of labelled...
