EMC Fibre Channel with QLogic Host Bus Adapters in the Solaris Environment
Installing and Configuring the HBA and Driver
Editing /etc/system
Operation in a Solaris environment requires that some parameters in
the file
/etc/system must be modified, as described in this section.
Note: Changes to /etc/system will not take effect until the host is
rebooted.
Note: The modification to the parameter sd_max_throttle is required
specifically for Fibre Channel. Other settings apply to both standard SCSI
and Fibre Channel.
1. Type set sd:sd_max_throttle=20 and press ENTER.
2. Add a line to set the I/O timeout. This setting prevents the host
from issuing warning messages when non-disruptive operations
are performed on the EMC storage array:
set sd:sd_io_time = 0x3C
What next? Reboot the host with the reconfigure option (reboot -- -r) to
rebuild the kernel and implement the changes.
Dynamically configured Targets/LUNs and driver parameters
The dynamic configuration of Targets/LUNs and/or driver
parameters without rebooting is supported on driver 4.15.03 or later.
The following restrictions must be considered prior to the start of
dynamically configuring Targets/LUNs or driver parameters:
◆ Logged on as root, or have an effective user ID of root.
◆ Ensure that the /kernel/drv/sd.conf file contains an entry:
name="sd" parent="qla2x00" target=0;
◆ If any persistent binding changes are made to currently mounted
partitions, unmount those partitions.
◆ Stop any application that is using the sdmapi interface (for
example, SNIA).
◆ The system utilities (for example, devfsadm, update_drv, pkill,
drvconfig, disks, and so forth, must be present on the host and
executable by root.
