Hi,
I have presented a LUN to a VM (RHEL 5.8) and need to scan the scsi bus in order for the OS to pick it up.
On FC attached hosts I can:
echo "1" > /sys/class/fc_host/host0/issue_lip
echo "- - -" > /sys/class/scsi_host/host0/scan
....but this does not work on my vm.

I recently got a Sun Sparc 10 Ultra with Solaris 10 installed on it. Now I'm trying to connect my SCSI Jaz drive to it. I moved my Adaptec AHA-2940U PCI SCSI card from my XP PC (where it was working OK) to the Sun and that's about as far as I got.
I did a probe-scsi-all and got nothing back,... (0 Replies)

VIAIDE(4) BSD Kernel Interfaces Manual VIAIDE(4)
NAME
viaide -- AMD, NVIDIA and VIA IDE disk controllers driver
SYNOPSIS
viaide* at pci? dev ? function ? flags 0x0000
options PCIIDE_AMD756_ENABLEDMA
DESCRIPTION
The viaide driver supports the following IDE controllers and provides the interface with the hardware for the ata driver:
- Advanced Micro Devices AMD-756, 766, 768 and CS5536 IDE Controllers
- NVIDIA nForce, nForce2, nForce2 400, nForce3, nForce3 250, nForce4, MCP04, MCP55, MCP61, MCP65, MCP67 IDE and SATA Controllers.
- VIA Technologies VT82C586, VT82C586A, VT82C596A, VT82C686A, VT8233A, VT8235, VT8237/VT8237R IDE Controllers, VT6421 Serial RAID
Controller and CX700 IDE Controller.
The 0x0002 flag forces the viaide driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debugging
aid, or to work around problems where the IDE controller is wired up to the system incorrectly.
SEE ALSO
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
NOTES
Drives on the VT6421 Serial RAID Controller can only be accessed after they have been configured into RAID or JBOD sets via its BIOS. It is
also inaptly named as it has both SATA and PATA interfaces.
BUGS
The AMD756 chip revision D2 has a bug affecting DMA (but not Ultra-DMA) modes. The workaround documented by AMD is to not use DMA on any
drive which does not support Ultra-DMA modes. This does not appear to be necessary on all drives, the PCIIDE_AMD756_ENABLEDMA option can be
used to force multiword DMA on the buggy revisions. Multiword DMA can eventually be disabled on a per-drive basis with config flags, see
wd(4). The bug, if triggered, will cause a total system hang.
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work
properly on overclocked systems.
