Emulex Driver for Linux and OneCommand Manager Application Situations

Table 6: Emulex Driver for Linux and OneCommand Manager Application Situations
Situation
FC link fails to come up.
The OneCommand Manager application
software package will not install. An error
message states that: "inserv Service Elxlpfc
has to be enabled for service
ElxDiscSrvinserv: exiting now/sbin/ inserv
failed exit code 1."
If a SAN configuration has 256 targets
mapped by the LPFC driver, any additional
added targets do not get a target ID mapping
by the driver and cause target discovery to
fail. Removing targets or reinitializing the link
does not solve the problem.
In some cases, after loading an OEM
supplied combined firmware/OpenBoot
image you will not be able to enable
BootBIOS from the lputil Boot BIOS
Maintenance menu.
rmmod fails to unload LPFC driver module
due to ERROR: Module LPFC is in use.
This message can appear when you attempt
to remove the driver and there is a Logical
Volume Group dependent on the driver.
Slow targets or extended link faults on the
storage side may result in storage being
marked off-line by the mid-layer and
remaining off-line (not recovered) when the
link faults are corrected.
Under certain conditions of an I/O load,
some targets cannot retire an I/O issued by a
Linux initiator within the default timeout of 30
seconds given by the SCSI midlayer. If the
situation is not corrected, the initiator-to-
target condition deteriorates into abort/
recovery storms leading to I/O failures in the
block layer. These types of failures are
preceded by a SCSI IO error of hex
6000000.
The OneCommand Utility User Manual
Resolution
For LP21000 adapters, ensure the adapter is not in
maintenance mode and that it is not running the manufacturing
firmware.
Reinstall the driver with the lpfc-install script.
Unload and reload the driver to reset available target IDs.
Ensure that the SAN configuration is correct prior to reloading
the driver. This will clear the driver's consistent binding table
and free target IDs for new target nodes.
1. Download the current OpenBoot only image for your adapter
from the Emulex web site.
2. Load the current OpenBoot only image following steps listed
in Updating BootBIOS section of this manual.
3. Run lputil, return to the Boot BIOS Maintenance menu.
4. Enable BootBIOS.
Make the Logical Volume Group unavailable.
Type: lvchange -a n xxxxxxx
where xxxxxx is the Volume Group Name.
The 8.2 version of the driver should eliminate this problem.
However, if you experience off-line device issues, increase the
SCSI command timeout to a value greater than or equal to sixty
seconds. Emulex also provides a script which addresses this
issue (for 2.6 kernels). To access the lun_change_state.sh
script, click
http://www.emulex.com/files/downloads/linux/tools.html, then
click the link to the appropriate driver, and click the Linux tools
link.
