iprdump - IBM Power RAID adapter dump utility SYNOPSIS
iprdump [-d directory] iprdump --version --debug --use-polling --use-uevents DESCRIPTION
iprdump is used to gather information in the event of an adapter failure. The dump data will by default be saved in the /var/log/ direc- tory with the prefix iprdump.# where # will be the dump ID of the file. The ipr dump utility will make a log in the system error log when a dump is taken. The iprdump utility can be started at any time and will properly handle adapters being dynamically added and removed from the system. OPTIONS
--version Print the version number of iprdump --debug Enable additional error logging. Enabling this will result in additional errors logging to /var/log/messages. -d <directory> Directory where dump data is to be stored. Default is /var/log/. --use-polling Do not use netlink/uevent notification, but rather poll for adapter and device configuration changes. --use-uevents Use netlink/uevent notification rather than polling for adapter and device configuration changes. If not specified, polling will be used until the first uevent notification appears, then netlink will be used. AUTHOR

savecore -- save a core dump of the operating system SYNOPSIS
savecore -c [-v] [device ...] savecore -C [-v] [device ...] savecore [-fkvz] [-m maxdumps] [directory [device ...]] DESCRIPTION
The savecore utility copies a core dump into directory, or the current working directory if no directory argument is given, and enters a reboot message and information about the core dump into the system log. The options are as follows: -C Check to see if a dump exists, and display a brief message to indicate the status. An exit status of 0 indicates that a dump is there, 1 indicates that none exists. This option is compatible only with the [-v] option. -c Clear the dump, so that future invocations of savecore will ignore it. -f Force a dump to be taken even if either the dump was cleared or if the dump header information is inconsistent. -k Do not clear the dump after saving it. -m maxdumps Maximum number of dumps to store. Once the number of stored dumps is equal to maxdumps the counter will restart from 0. -v Print out some additional debugging information. Specify twice for more information. -z Compress the core dump and kernel (see gzip(1)). The savecore utility looks for dumps on each device specified by the device argument(s), or on each device in /etc/fstab marked as ``dump'' or ``swap''. The savecore utility checks the core dump in various ways to make sure that it is complete. If it passes these checks, it saves the core image in directory/vmcore.# and information about the core in directory/info.#. For kernel textdumps generated with the textdump(4) facility, output will be stored in the tar(5) format and named directory/textdump.tar.#. The ``#'' is the number from the first line of the file directory/bounds, and it is incremented and stored back into the file each time savecore successfully runs. The savecore utility also checks the available disk space before attempting to make the copies. If there is insufficient disk space in the file system containing directory, or if the file directory/minfree exists and the number of free kilobytes (for non-superusers) in the file system after the copies were made would be less than the number in the first line of this file, the copies are not attempted. If savecore successfully copies the kernel and the core dump, the core dump is cleared so that future invocations of savecore will ignore it. The savecore utility is meant to be called near the end of the initialization file /etc/rc (see rc(8)). SEE ALSO

The savecore utility appeared in 4.1BSD. Support for kernel textdumps appeared in FreeBSD 7.1. BUGS
The minfree code does not consider the effect of compression or sparse files. BSD
