Setup Procedure for QLogic Fibre Channel Cards

3.5

Required Driver Parameters

# When the Persistent Name Binding entries are used in combination

# with the device entries in the /kernel/drv/sd.conf or

# /kernel/drv/st.conf file, it is possible to purposely mask off

# certain devices of all adapter instances from the operating system,

# by purposely commenting out/deleting entries in the sd.conf/st.conf

# file for those SCSI target IDs/LUNs bound to all adapter instances.

However, when the devices are shared among multiple adapters,

# doing so requires extreme caution, and it is strongly recommended

# that all target devices be bound with all adapter instances so that

# the devices will show up in a predeterminable way.

# which is bound on one adapter instance but unbound on another

# adapter instance may show up at a SCSI target ID which is

# unexpected by the user for the unbound adapter instance, which may

# lead to possible data corruption on the device if the user

# unknowingly writes to the unexpected device.

# The QLogic Solaris SCSI HBA driver does not filter out the OS

# scanning of SCSI devices, except when the "Persistent Binding

# Only Option" is set. The target IDs/LUNs scanned by the OS are

# based on the entries specified in the sd.conf and st.conf files.

# When the HBA driver first initializes during the system boot

# process, it assigns a target ID internally to all of the devices it

# detected. During the OS device scan, the driver ignores the 'class'

# value indicated in the sd.conf/st.conf file and processes the IOs

# addressed to a device whose target ID/LUN matches that of a device

# previously detected by the driver.
