By examining the Protocol options bits (which corresponds to the TPF bits in the table above), you can see that this
device is currently configured for U160 mode.
Detecting Link Speed for Fibre Channel Peripherals
You can determine the link speed for fibre channel drives by using the -fchbainfo command which is part of
the SAN Reporting capability in this software.
Detecting Link Speed for SAS Peripherals
You can determine the link speed by looking at the highlighted negotiated link rate field in the sample output for
mode page 19 .
1.21 Log Page Viewer
Like Mode Pages, SCSI family devices (remember, this includes FC and SAS peripherals) will typically have log
pages. These log pages are used to report cumulative totals. These totals may be used to assist the administrator in
tuning efforts, error diagnosis, or administration tasks. The ANSI SCSI specifications allow for hundreds of log pages,
as well as vendor-specific pages. To further complicate the issue, as new ANSI specifications come out, they will add
new log pages, and possibly retire others.
We make an effort to maintain internal tables of both ANSI defined log pages, and vendor specific pages as well. As
release levels of the code increase, additional vendor/model specific entries are always added. As log and mode page
settings are sometimes vendor specific and are only released under NDA, it sometimes takes us time to get
permission and the necessary information to report these settings to you.
To view all the mode pages for a particular device, in hex, enter
/etc/smartmon-ux -C /hw/scsi/sc2d66l0

/etc/smartmon-ux -C+ /hw/scsi/sc2d66l0

On our IRIX development system, the device reported the below:
