Overview: The Next Generation Mass Storage Stack (September 2009)

42
insf(1M)
Installs special (device) files.
-L Enables legacy addressing by restoring legacy DSFs (if
legacy view was disabled with rmsf –L)
-Lv Displays whether the legacy mode is enabled or disabled
lssf(1M)
Lists special files.
-s Lists stale special files
-c dsf Performs a critical resource analysis on a DSF
mksf(1M)
Makes a DSF.
-P Creates a pass-through persistent DSF for the esdisk,
estape, and eschgr drivers
rmsf(1M)
Removes a DSF.
-u –H hwpath Unbinds driver at a specified LUN hardware path
-x Removes stale entries from the I/O configuration file
-L Disables legacy addressing mode by removing legacy DSFs
and legacy I/O configuration information
ioinit(1M)
Maintains consistency between kernel I/O data structures and I/O configuration
files.
-rC class Reassigns device instance numbers, starting from 0, for a
specified device class
-v ioconfig_file Checks an I/O configuration file for corruption
-A Performs Critical Resource Analysis (CRA) on all the devices
corresponding to the hardware paths specified in infile. You
must use this with the –f option.
mediainit(1M)
Formats and scrubs a mass storage device.
-S Scrubs the specified disk three times.
-c scrub_character Specifies the character to use for disk scrubbing. You must
use this with the –S option.
-t scrub_count Specifies the number of passes for a disk scrub. You must use
this with the –S option.
special file Specifies the character device special file of the disk to be
scrubbed.
