3.7.0 HP StorageWorks HP Scalable NAS File Serving Software installation guide HP Scalable NAS for Linux (AG513-96004, October 2009)

For more information, see the section “Host Bus Adapters (HBAs)” in the HP Scalable
NAS File Serving Software administration guide. Do not start HP Scalable NAS after
installing the driver.
If you need to enable the failover feature provided with the QLogic HBA driver, see
the section “Other MPIO support” in the HP Scalable NAS File Serving Software
administration guide.
NOTE:
The /etc/hba.conf file must point to the correct hbaapi library.
13. Reboot and verify the HBA configuration
Reboot the server. After the reboot, check for HBA drivers in the configuration. Note
the following:
• If you removed the HBA modules from the appropriate operating system file, no
HBA drivers should be loaded after the server is rebooted. (When HP Scalable
NAS is started, it will load the HBA driver.)
• If you will be using third-party MPIO or will be booting from the SAN, the kernel
should have loaded the HBA driver.
Use the following commands to verify your configuration.
1. Run the command corresponding to your HBA type to determine whether an
HBA driver was loaded when the kernel rebooted:
# lsmod | grep lpfc
# lsmod | grep qla
2. If lsmod reports that an HBA driver was loaded, use one of the following
commands to check the driver version. The version will appear in the first few
lines.
Emulex:
# cat /sys/class/scsi_host/host<adapter>/lpfc_drvr_version
QLogic:
# cat /proc/scsi/qla2xxx/<adapter> | more
