Specifications

4. If you attach the ESS to a Sun host through a PCI SCSI adapter, continue to
step 5. If not, skip to step 7.
5. If the glm.conf file exists, back it up to the /kernel/drv subdirectory.
6. If you are running Solaris 2.6, edit the glm.conf file and add the following lines
to enable support for LUNs8-32:
device-type-scsi-options-list=
"IBM 2105F20 ", "ibm-scsi-options";
ibm-scsi-options = 0x107f8;
If you run Solaris 2.7 or Solaris 8, edit the glm.conf file and add the following
lines to enable support for LUNs8-32:
device-type-scsi-options-list=
"IBM 2105F20 ", "ibm-scsi-options";
ibm-scsi-options = 0x407f8;
Note: The ESS inquiry information in these examples (IBM 2105F20), must
include eight characters of vendor information (IBM and five spaces).
These characters are followed by 16 characters of product information
(2105F20 and nine spaces). The examples show the inquiry data for the
IBM 2105 Model F20. The actual product information must match the
model being attached.
7. Type reboot -- -r from the Open Windows panel to shut down and restart the
Sun host system with the kernel reconfiguration option. Or, type boot -r from
the OK prompt after you shut down.
Descriptions for setting the scsi_options in /etc/system file
You can configure the scsi_options variable in the Solaris 2.x kernel to enable or
disable particular capabilities. For example, you can set the scsi_options variable in
the /etc/system file. The default scsi_options variable allows the widest range of
capabilities that the SCSI host adapter provides.
The default scsi_options value on Solaris 2.x works for 5-MB and 10-MB devices.
The driver negotiates with each device to determine if it is capable of transferring
10-MB or not. If they are 10- MB devices, 10-MB transfer rate will be used. If not, a
5-MB transfer rate will be used.
