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
