SAS Controllers HP SC44Ge SAS Host Bus Adapter NOTE: Recommended SAS HBA for connecting HP StorageWorks tape drives to HP ProLiant servers. 416096-B21 HP Smart Array P400/256MB Controller 405132-B21 HP Smart Array P400/512MB Controller 411064-B21 HP 8 Internal Port SAS HBA with RAID 0/1 NOTE: PCI-X interface 347786-B21
The P212 Smart Array controller is fully supported and should work fine. The only side note for the card is that for best performance you should install the optional cache memory module.
What firmware is in the P212?
During boot what exactly does it show? The P212 doesn't list tape drives in detail instead it just says "tape or CDROM found at xx".
Do you have anything else hooked up to the P212 and does it communicate correctly?
Do you know what firmware is in the 1760? Some really early 1760 drives were not able to be detected by the P212 and there was a firmare update. That has been a long time ago though.
If you have a way to create a firmware update tape I would recommend you update the firmware in the tape drive.
If everything is running in a supported config, I have seem that some LSI has a BIOS where you can configure the boot process. This is a known issue in SAS drives and below you will find a link explaining how it can be resolve:
