###Replace the LSI SAS 2008 controller with a Highpoint Rocket 2720SGL.
Replace the LSI SAS 2008 controller with a Highpoint Rocket 2720SGL.
This Rocket 2720SGL adapter contains a Marvell 4.0.0.15 BIOS. This BIOS won't spinup the PUIS/POIS drives.
That is not a problem because the HighPoint Marvell 4.0.0.1528N open source Linux driver its make command does create a mv94xx.ko kernel module that is able to spinup the PUIS/POIS drives, also behind a HP SAS expander V2.08. Now there are /dev/sdXX devices available in Debian.
As a result the Marvell BIOS can be disabled, which shortens boot time.
Note#1: The Highpoint Rocket 2720SGL is not a RocketRAID 2720SGL.
The RocketRAID contains a Highpoint BIOS, the Rocket contains a Marvell BIOS.
Note#2: Using another Marvell 88SE9485 based chip [1b4b:9485], like Supermicro SAS2LP-MV8, with a stock mvsas.ko module (version 0.8.16, Marvell 88SE6440 SAS/SATA controller driver) hangs the kernel when connecting drives on ports 6C, 7C and 8C of a HP SAS expander and "Failed to get diagnostic page 0x8000002", "Failed to bind enclosure -19" on ports 5C and 9C when running recent kernel versions like Ubuntu 3.12.25, 3.13.0, 3.13.11, 3.16.0rc6 and 3.16.0-999 dated 24072014.
