iscsid - establish and maintain iSCSI connections


SYNOPSIS

       iscsid


DESCRIPTION

       iscsid  establishes  and  maintains connections with iSCSI
       targets defined in /etc/iscsi.conf.

       Once the Linux iSCSI driver is activated, the client  will
       proceed with a discovery process for iSCSI storage devices
       as follows:

       - The iSCSI daemon requests available iSCSI  targets  from
       the canonical iSCSI target.

       - The client establishes connections to the targets.

       - The client queries targets for device information.

       -  The  client creates a mapping from SCSI device nodes to
       iSCSI targets.

       iscsid should be started after  networking  is  configured
       and stopped after all iSCSI devices have been unmounted.

       Making  changes  to  your storage configuration, including
       adding or removing targets or LUNs, remapping targets,  or
       modifying  target  access,  may change how the devices are
       presented to the client. This  may  require  corresponding
       changes  in  your  iSCSI  driver  configuration  and  your
       filesystem table (/etc/fstab).

       Warning: Data corruption can occur if you do  not  unmount
       iSCSI devices before disabling network interfaces!


NOTES

       The  Linux  iSCSI driver currently provides IP access to a
       maximum of eight remote SCSI  targets,  with  each  target
       capable  of supporting 32 LUNs. Remote SCSI targets can be
       accessed through one or more storage routers up to a maxi­
       mum of eight storage routers.

       The  iSCSI  client drivers, README files, and example con­
       figuration files are available on the Linux-ISCSI homepage
