IBM Flex System V7000 Storage Node Introduction and Implementation Guide
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 12-4 the HBA adapters are shown as fcs0 and fcs1.
adapter. In Example 12-4 the HBA adapters are shown as fcs0 and fcs1.
Example 12-4
# lsdev -Cc adapter | grep fcs
fcs0 Available 05-00 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
fcs1 Available 05-01 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
fcs0 Available 05-00 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
fcs1 Available 05-01 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
Check 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 12-5. From this example we can see that the settings are as they should be.
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 12-5. From this example we can see that the settings are as they should be.
Example 12-5 Check HBA settings
# lsattr -El fscsi0
attach switch How this adapter is CONNECTED False
attach switch How this adapter is CONNECTED False
dyntrk yes
Dynamic Tracking of FC Devices True
fc_err_recov fast_fail
FC Fabric Event Error RECOVERY Policy True
scsi_id 0x10e00 Adapter SCSI ID False
sw_fc_class 3 FC Class for Fabric True
# lsattr -El fscsi1
attach switch How this adapter is CONNECTED False
sw_fc_class 3 FC Class for Fabric True
# lsattr -El fscsi1
attach switch How this adapter is CONNECTED False
dyntrk yes
Dynamic Tracking of FC Devices True
fc_err_recov fast_fail
FC Fabric Event Error RECOVERY Policy True
scsi_id 0x10e00 Adapter SCSI ID False
sw_fc_class 3 FC Class for Fabric True
sw_fc_class 3 FC Class for Fabric True
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:
enable fast fail on fcs0 FC SCSI I/O Controller Protocol Device issue command:
chdev -l fscsi0 -a fc_err_recov=fast_fail
