NAME
samfsconfig - Recovers configuration information
SYNOPSIS
/opt/SUNWsamfs/sbin/samfsconfig [-b] [-d] [-h] [-s] [-v]
device [device] ...
AVAILABILITY
SUNWqfs
SUNWsamfs
DESCRIPTION
The samfsconfig utility opens the device(s) listed on the
command line, attempts to read the Sun QFS file system
superblock on each, and generates output in a format similar
to an editable mcf(4) file. A Sun QFS file system
superblock is a record that the sammkfs(1M) utility writes
to the beginning of every device in a Sun QFS file system.
This record identifies the devices to the file system.
By default, the output is written to stdout, but the output
can be redirected to a file and edited to regenerate the
file system portions of the mcf file in the event of a
system reconfiguration or disaster.
samd buildmcf executes samfsconfig to build the mcf file.
samd config must be executed to reconfigure the changes
after the samd buildmcf has built the mcf file.
OPTIONS
This command accepts the following options:
-b Lists the size of the associated partition,
according to its superblock, in the last output
column. This may be useful when multiple disk
partitions of different sizes start at the same
offset.
-d Generates detailed information about all the Sun
QFS superblocks found, including the content of
each superblock.
-h Generates a usage message and exits.
-s Print the host file contents of QFS shared
filesystems.
-v Generates messages regarding the disposition of
each device.
device One or more device identifiers from which
configuration information is to be recovered. Use
a space character to separate multiple device
identifiers on the command line.
It can be desireable to save a list of device
identifiers to a file and use this file for
command line input to the program.
The samfsconfig utility generates information about all the
Sun QFS file systems and file system components it finds.
The file system name, creation time, generation, devices
count, and metadata devices count are listed. The
samfsconfig utility flags irregularities as follows:
o For any incomplete devices that have superblocks, but are
in an file system where all the devices are not present,
it prefixes a pound sign (#) to indicate problems.
o For any duplicate devices that have the same superblock
information with the same file system generation number,
it prefixes a greater-than sign (>). This is common if,
for instance, multiple paths exist or whole disk
partitions are specified on the command line.
o For devices, one /dev/did/dsk and the other device
/dev/dsk, which have the the same superblock information
with the same file system generation number, it prefixes a
greater-than sign (>) for the /dev/dsk devices. This
occurs for did file systems. This line is only generated
when the -v option is specified.
o For any duplicate devices that have the same superblock
information but have different file system generation
numbers, it prefixes a less-than sign (<). This can occur
if a device has been removed from the file system and a
new device has been added to the same file system in the
same ordinal position. Note, the file system generation
number is incremented when a device is added to the file
system. This line is only generated when the -v option is
specified.
