iMac having trouble recognizing HP LTO-7 Ultrium 15000
on Jul 16, 2019 at 6:45:17 pm

Hi,

I have an HP LTO-7 Ultirum 15000 that I am connecting to my I Mac (Retina 5k, 27-inch, Late 2015) macOS Mojave 10.14.5

I am connecting through a Highpoint RocketStor 6328 via miniSAS to Thunderbolt.

I am unable to have the tape deck recognized in either HPE StoreOpen Standalone or PreRoll Post

Any help on how I can get this deck recogonized would be greatly appreciated.

Thanks

From Yoyotta's LTO+LTFS FAQ page...

Highpoint RocketStor and RocketRAID devices are not compatible with LTFS + LTO drives.
The Highpoint 6328L is a SATA protocol interface. It has Mini-SAS connectors, but does not support SAS protocol. So this does not work with any SAS RAID or tape devices.
The Highpoint 6328 is a SAS protocol interface. But it does not support TLR protocol, so it cannot be used with LTO + LTFS.
We do not know of any fix for the HighPoint 6328, so this is not suitable for use with LTO-7, LTO-8 and LTFS.

Thank you Neil,

I spoke with ATTO and they recommended their ThunderLink TLSH-3128-D00. I would need an SFF-8644 to SFF-8088 cable as well as a thunderbolt TB2 to TB 3 converter. Has there been any issues using these thunderbolt converters, or is there possible a substitute that uses Thunderbolt 2 without the need for a converter.

Thank you so much

Although I haven't used a ThunderLink TLSH-3128 with LTO, I have used a Sonnet Thunderbolt 3 to PCIe expander and a Atto SAS H1280 inside that. This uses a Thunderbolt3 to Thunderbolt2 adapter to enable connecting to a Thunderbolt 2 Mac like yours. And it uses a SFF-8644 to SFF-8088. Both work fine with Bru as well as Yoyotta.

My system is connected as
MacBook Pro 2016 > TB2-TB2 cable > Apple TB3-TB2 adapter > Sonnet Express SEII with TB3 ports > Atto SAS H1280 > SFF-8644 to SFF-8088 cable > LTO-7 tape drive.

This has been working for over a year now. 40+ tapes, 150+TB data.
