Emulex OneCommand Manager Application User Manual (P006979-01A Version 5.2, August 2011)

The OneCommand Manager User Manual Page 262
The Linux SCSI subsystem only sees 8
LUNs when more are present.
Some SCSI drivers will not scan past 8 LUNs when the target
reports as a SCSI-2 device. Force a SCSI bus scan with
/usr/sbin/lpfc/lun_scan. SuSE supplies /bin/rescan-scsi-bus.sh
which can be changed to scan everything.
Cannot see any adapters. Try the following solutions:
1. Perform an 'lsmod' to see if the Emulex drivers are loaded.
Look for an error message on the command line stating the
LPFC driver is not loaded. If this is the case, do an insmod of
the LPFC driver and re-launch the OneCommand Manager
application.
2. Exit the OneCommand Manager application and run the
following sripts in this order:
1.) /usr/sbin/ocmanager/stop_ocmanager - stops the
OneCommand Manager application daemons
2.) /usr/sbin/ocmanager/start_ocmanager - starts the
OneCommand Manager application daemons
3.) /usr/sbin/ocmanager/ocmanager - starts the
OneCommand Manager application gui
The adapters should be visible. If they are not visible, reboot
your system.
Cannot see other adapters or hosts.
Although the OneCommand Manager
application is installed, only local adapters
are visible. The other adapters and hosts in
the SAN cannot be seen.
All the adapters in the SAN will be visible if:
• The other servers have a connection to your zone of the
SAN. Check fabric zoning.
• The elxhbamgr processes are running on remote hosts (enter
ps -ef | grep elxhbamgr).
• All other adapters are running the OneCommand Manager
application and the appropriate driver.
• The other adapters are Emulex adapters.
Note: The OneCommand Manager application services must be
running on all remote hosts that are to be discovered and
managed.
Cannot see new LUNs. Try the following:
1. Click the Refresh LUNs button in the toolbar.
2. Exit the OneCommand Manager application and restart the
OneCommand Manager application. If new LUNs are visible,
you are finished.
If that doesn't work, try the following:
1. Exit the OneCommand Manager application.
2. Navigate to /usr/sbin/ocmanager.
3. Run ./stop_ocmanager to stop both the elxhbamgr and
elxdiscovery processes.
4. Run ./start_ocmanager and ./start_elxdiscovery to restart
both processes.
5. Start the OneCommand Manager application.
