Installing and Configuring the QLogic HBA and v8.x-Series Driver

Additional notes

Device reconfiguration: procedures

The Linux v2.6.x kernel lacks a command built into the kernel that

allows for a dynamic SCSI bus reconfiguration such as drvconfig or

ioscan.

The SCSI bus may be rescanned with a system reboot, or with a

removal and reinsertion of the modular driver. In either case, all I/O

must be stopped and all other mounted filesystems must be

unmounted before rebooting or removing the modular driver.

Note: In the Linux v2.6.x kernel, the HBA numbers will increment in the

/proc filesystem with each re-insertion of the QLogic driver.

Rebooting the host

Rebooting the host allows for reliable detection of newly added

devices. The host may be rebooted after all I/O has stopped.

Unloading and reloading the modular QLogic driver

◆ Stop all I/O.

◆ Unmount all file systems attached to the QLogic driver.

◆ f the Naviagent/CLI is installed and enabled on the host, then the

Naviagent/CLI service must be stopped.

To stop the Naviagent/CLI service, issue one of the two following

commands:

/etc/init.d/naviagentcli stop

service naviagentcli stop

◆ If PowerPath is installed and enabled on the host, then the

PowerPath service must be stopped.

To stop the PowerPath service, issue one of the two following

commands:

1 2 ... 49 50 51 52 53 54 55 56 57 58 59 ... 75 76
