superloopy1 Posted May 19, 2020 Posted May 19, 2020 Hello ... i was nearly at the limit of devices and went for an upgrade to Pro, now installed. I have 10 array devices currently, one cache drive and one unassigned device, a total of 12 drives. When i try to add another unassigned device my system just hangs and i need to remove an external drive and reboot ok. Does this indicate a problem with my licencing? There doesnt seem to be anything in the logs, no errors of any sort. Is there any thing i need to dow ith UD to allow more than one drive (i am trying to preclear a couple of 12TB drives simultaneously ... I know!) Anything i'm missing here? Quote

Does this indicate a problem with my licencing? No, sounds like a BIOS issue. Some BIOS's lose their mind when they have too many bootable devices attached. If you are using a HBA of some flavor you can try disabling its boot capability. Quote
superloopy1 Posted May 21, 2020 Author Posted May 21, 2020 Thanks for your interest ... i've had no issues until now when i've just added my 13th drive which just happens to be an unassigned device that i'm wanting to preclear. The system just hangs with nothing in the logs. I remove the drive and it boots, strange. I can preclear on another system but can foresee problems when i come to add in the drive soon. Quote
itimpi Posted May 21, 2020 Posted May 21, 2020 Are you using a HBA? If so have you disabled the option to boot from HBA attached drives? I have come across cases where the BIOS gets confused if it finds more than 12 devices that could be potential boot devices. Quote
superloopy1 Posted May 22, 2020 Author Posted May 22, 2020 Thanks. I think this could be the cause, i'l take a look next time the server is rebooted. I'll need to fig out the appropriate hardware, the server has ran headless for years. I'll post an update ... Quote
superloopy1 Posted May 25, 2020 Author Posted May 25, 2020 And .... that sorted it! Must admit I just chucked in both hbas a few years back never expecting to hit 125TB. Once disabled all 14 drives accessible, many thanks! 1 Quote
