Operating System Versions And Maintenance Levels - IBM V7000 Introduction And Implementation Manual

4. Check the FC switch zoning.
5. Install the 2145 host attachment support package,
6. Install and configure the Subsystem Device Driver Path Control Module (SDDPCM).
7. Run cfgmgr or reboot the compute node to discover and configure the IBM Flex System
V7000 Storage Node volumes.
Checking HBAs in the compute node
You can display the availability of installed host adapters by using the command lsdev -Cc
adapter. In Example 12-6, the HBA adapters are shown as fcs0 and fcs1.
Example 12-6
# lsdev -Cc adapter | grep fcs
fcs0
fcs1
Checking HBA settings
Some settings on the HBAs differing from the default are recommended, for example, both
fast fail and dynamic tracking should be enabled. To check these parameters issue the
following command to the FC SCSI I/O Controller Protocol Device of each adapter as show in
Example 12-7. From this example we can see that the settings are as they should be.
Example 12-7 Check HBA settings
# lsattr -El fscsi0
attach
dyntrk
fc_err_recov fast_fail
scsi_id
sw_fc_class 3
# lsattr -El fscsi1
attach
dyntrk
fc_err_recov fast_fail
scsi_id
sw_fc_class 3
If one of these settings required changing the chdev command would be used, for example, to
enable fast fail on fcs0 FC SCSI I/O Controller Protocol Device issue command:
chdev -l fscsi0 -a fc_err_recov=fast_fail

12.5.2 Operating system versions and maintenance levels

The following section details the current support information. It is vital that the websites that
listed are checked regularly for any updates.
Presently, the only FC HBA supported on the p260 and p460 compute nodes is the IBM Flex
System FC3172 2-port 8 Gb FC Adapter, see SSIC to verify supported configurations:
