sysfs.
<Host number> | <-a/--all> [optional]
Provide the <HOST NUMBER> to display the detailed information of the HBA. With no option specified, general information of all
hosts will be displayed. Ex. # /usr/sbin/ql-hba-snapshot <Host Number> # /usr/sbin/ql-hba-snapshot --procfs <Host Number> (For
procfs)
-h, --help
Prints the help message. Ex. # /usr/sbin/ql-hba-snapshot --help
-hl, --hostlist
This option displays the list of QLogic hosts (HBAs) connected to this system. The <HOST NUMBER> can be obtained by using following
command Ex. # /usr/sbin/ql-hba-snapshot --hostlist
-p, --parameters
This option displays the command line parameters that can be passed to the QLogic HBA driver. Ex. # /usr/sbin/ql-hba-snapshot
--parameters <Host Number>
-s, --statistics
This option displays the statistical information for specified host. Stastics option is only supported in "sysfs" based scan. Ex.
# /usr/sbin/ql-hba-snapshot --statistics <Host number/--all>
-proc, --procfs
