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 did a probe-scsi-all and got nothing back,... (0 Replies)

DESCRIPTION
Devices commonly known for their use on PC devices as ATA or IDE devices are supported using the SCSI CAM device driver. The ATA standard
has also been expanded to include what are known as ATAPI devices. The SCSI CAM device driver is also used for those disks and CD-ROM
devices. These devices may also be known under the names EIDE, ATA-2, Fast-ATA, or Ultra-ATA.
Beacuse the ATA/IDE standard was not developed until after many of the devices that used this standard were produced, there are many
devices which do not strictly comply with the standard. While it is possible some industry standard devices may appear to work, it is also
possible they will cause hang or data corruption cases when used under more stressful situations. For this reason, it is recommended that
only the supported devices be used. These devices have been tested and are certified for correct operation.
ATAPI/IDE controllers allow the connection of two devices. These two devices are known as the master device and the slave device. If only
one device is connected, that device must be the master (slave-only configurations are not supported). When used by the SCSI CAM device
driver, the IDE master device is assigned SCSI id 0 for that controller. The slave device is assigned SCSI id 1 for that controller. No
other SCSI ids are assigned on that controller. Most ATAPI/IDE adapters contain two channels (known as the primary and secondary). Each
of these channels may contain their own master and slave devices. Therefore, a dual channel ATAPI/IDE controller may contain up to 4
devices (a master and slave pair on each channel). These 4 devices are then accessed as SCSI id 0 and 1 on each channel.
Many SCSI operations translate perfectly for use on IDE. For example, read and write operations are the same. However, many SCSI disk
mode pages are emulated by the IDE device driver. For example, you can display the SCSI inquiry mode pages using the following command: %
scu show inq pages pages are created by the device driver to contain the long (full IDE) form of the device name, serial number, revision,
and the operational modes of the device. Only a shortened version of this information is available with the standard SCSI inquiry command.
Note also that the following command: % scu show pages Shows that the SCSI mode pages contain only partial information. Only that informa-
tion (such as geometry) that the drive reports to the system is able to be reformatted into these emulated SCSI mode pages. Much of the
information (such as RPM) is simply not available from the drive, and therefore not accurately reported.
ATAPI devices are much more closely related to SCSI devices, and as such contain their own mode pages. Therefore, for these devices, the
mode page values reported are those from the device, and no emulation is involved.
ATAPI tape devices are not supported at this time.
