Specifications

4. Type reboot ---r from the Open Windows window to shutdown and restart the
Sun host system with the kernel reconfiguration option. Or, type boot -- -r
from the OK prompt after you shutdown.
The fibre-channel adapters that are supported for attaching the ESS to a Sun host
are capable of full-fabric support. IBM recommends that all fibre-channel driver
configurations include worldwide port name, worldwide node name, port ID, or
host-bus-adapter binding of target LUN pairs.
Binding of target LUN pairs implements the Solaris SCSI driver configuration file or
the fibre-channel host-bus-adapter configuration file installed by the adapter
software package. Refer to the vendor adapter documentation and utilities for
detailed configuration instructions.
You can tune fibre-channel host-bus-adapter configuration files for host system
reliability and performance.
See Table 21 for recommended host bus adapter configuration file parameters for
an Emulex LP-8000 adapter.
Table 21. Recommended configuration file parameters for the host bus adapters for the
Emulex LP-8000 adapter
Parameters Recommended settings
automap 1: Default. Automatically assigns SCSI IDs to fibre-channel protocol
(FCP) targets.
fcp-on 1: Default. Turn on FCP.
lun-queue-depth 16: Recommended when there are less then 17 LUNs per adapter.
Set value = 256/(total LUNs per adapter) when there are more than
16 LUNs per adapter. If your configuration includes more then one
LP8000 adapter per server, calculate the LUN-queue-depth value
using the adapter with the most LUNs attached.
no-device-delay 15: Recommended. Delay to failback and I/O.
network-on 0: Default. Recommended for fabric. Do not turn on IP networking.
1: Turn on IP networking.
scan-down 2: Recommended. Use an inverted ALPA map and create a target
assignment in a private loop.
topology 2: Recommended for fabric. Point-to-point mode only.
4: Recommended for nonfabric. Arbitrated loop mode only.
zone-rscn 0: Default
1: Recommended for fabric. Check name server for RSCNs.
See Table 22 for the recommended configuration settings for the host-bus-adapter
for a JNI FC64-1063 and a JNI FCI-1063.
Table 22. Recommended configuration file parameters for the host bus adapters for the JNI
FC64-1063 and JNI FCI-1063.
Parameters Recommended settings
fca_nport 0: Default. Initializes on a loop
1: Recommended for fabric. Initializes as an N_Port.
