Emhttp not recognizing disks on AOC-SASLP-MV8

[joelones]

Guys,

 

I'm at my wits end here with a custom install of Slackware and unRAID 4.6. The base system is Slackware -current and I've compiled the drivers from https://scst.svn.sourceforge.net/svnroot/scst/trunk. The following steps have been taken:

 

1. Compiled kernel 2.6.32.9 without mvsas support but libsas support. In terms of the scsi options, my .config matches the one found in the 4.6 distro. It is as follows:

 

CONFIG_SCSI=y
CONFIG_SCSI_DMA=y
CONFIG_SCSI_WAIT_SCAN=m
CONFIG_SCSI_SAS_ATTRS=m
CONFIG_SCSI_SAS_LIBSAS=m
CONFIG_SCSI_SAS_ATA=y
CONFIG_SCSI_SAS_HOST_SMP=y
CONFIG_SCSI_SAS_LIBSAS_DEBUG=y
CONFIG_SCSI_LOWLEVEL=y
CONFIG_SCSI_3W_9XXX=m
CONFIG_SCSI_AACRAID=m
CONFIG_SCSI_ARCMSR=m

 

2. Compiled and installed drivers from scst:

 

svn co https://scst.svn.sourceforge.net/svnroot/scst/trunk

patch -p1 <path to scst trunk>/scst/kernel/scst_exec_req_fifo-2.6.32.patch (prior to step 1)

make scst
make scst_install
make mvsas
make mvsas_install

 

 

3. Boot system and run emhttp. Loaded modules:

dm_mod                 42102  0

sata_sil24              8688  2 
ata_piix               17052  0 
ext2                   34888  1 

 

Drives connected are visible to OS but emhttp does not see them.

 

4. The mvsas_tgt directory contains a README with info to configure the device, so maybe I'm missing some configuration?

 

> modprobe libsas
> insmod mvsas.ko
> echo 1 >/sys/class/scsi_host/host4/target_mode
> echo "add 4:0:0:0 0" >/proc/scsi_tgt/groups/Default/devices

 

I tried the above but got stumped at the fourth line as the directory /proc/scst_tgt does not exist

 

 

Finally, I noticed some warnings in the logs that could perhaps be the culprit?

 

[817]: scst: __scst_register_target_template:245:***WARNING***: Target driver mvst_scst doesn't support Persistent Reservations
[817]: scst: __scst_register_target_template:262:***WARNING***: Target driver mvst_scst doesn't have enable_target() and/or is_target_enabled() method(s). This is unsafe and can lead that initiators connected on the initialization time can see an unexpected set of devices or no devices at all!

Any help is graciously appreciated and welcomed.
