NAME

       aoe-flush - flush the down devices out of the aoe driver

SYNOPSIS

       aoe-flush [-a]
       aoe-flush dev1 [dev2 ...]

DESCRIPTION

       The  aoe-flush command tells the aoe driver to remove devices from the system and forget about them.  Normally the aoe driver will remember
       all devices it has seen until the module is unloaded.  By default, aoe-flush will only flush downed devices.  With the -a flag all  devices
       are candidates for removal.

       aoe-flush  will	not  remove  devices  that  are  in  use.   This  includes devices in the closewait state or those in the process of being
       installed.

       By specifying a series of specific aoe devices, e.g., e7.0 e3.2, it is possible to ask the aoe driver to forget these devices.	This  fea-
       ture may be convenient after a temporary AoE target is no longer being used.

OPTIONS

       -a     The -a option tells the aoe driver to forget all unused devices.

EXAMPLE

       nai# aoe-stat | grep e12.0
	    e12.0	  0.000GB   eth1 down
       nai# aoe-flush
       nai# aoe-stat | grep e12.0

BUGS

       Flushed devices may reappear when they are discovered by the periodic discovery beacon.	aoe-discover may be used to force this behaviour.

aoe-mkshelf(8)						      System Manager's Manual						    aoe-mkshelf(8)

NAME

       aoe-mkshelf - create special device files for one shelf address

SYNOPSIS

       aoe-mkshelf {device-dir} {shelf-address}
       env n_partitions=1 aoe-mkshelf {device-dir} {shelf-address}

DESCRIPTION

       The  aoe-mkshelf  command  is not needed on systems that have udev installed and is incompatible with aoe drivers that have the aoe_dyndevs
       module parameter set to 1.

       Systems lacking udev and having an aoe driver that uses static minor device numbers can use aoe-mkshelf to create the block  special  files
       necessary to access the AoE devices with the given shelf address.

       All  aoe  drivers  prior  to  aoe6-50 use static minor device numbers.  Versions 50 and up use dynamic minor device numbers when the module
       parameter aoe_dyndevs=1 is set.

       If you are using static minor device numbers and your aoe driver supports only one partition per device (whole-disk partitions),  then  the
       device files must match, and you should use the n_partitions environment variable described below.

   Arguments
       device-dir
	      This should be the name of the directory where the block device files will be created.

       shelf-address
	      This  is	the  AoE  major address, or shelf address, for which to create device nodes.  For example, specifying a shelf address of 1
	      means that the e1.* device nodes will be created in device-dir.

ENVIRONMENT VARIABLES

       If the n_partitions variable is set in the environment, it will override the default number of partitions per aoe disk, namely 16.

EXAMPLE

       In this example, the root user on a host named nai creates special files for using the aoe disks in shelf 7.  Then he  remembers  that  the
       driver doesn't have partition support, so the command is called again with n_partitions set to 1.

	      nai:~# aoe-mkshelf /dev/etherd 7
	      nai:~# ls /dev/etherd/e7.* | wc -l
	      160
	      nai:~# rm /dev/etherd/e7.*
	      nai:~# n_partitions=1 aoe-mkshelf /dev/etherd 7
	      nai:~# ls /dev/etherd/e7.* | wc -l
	      10
	      nai:~#
