iscsid -- interface to kernel iSCSI driver SYNOPSIS
iscsid [-n] [-d lvl] DESCRIPTION
The iSCSI initiator runs as a kernel driver, and provides access to iSCSI targets running across a network using the iSCSI protocol, RFC 3720. The iscsid utility itself interfaces to the kernel iSCSI driver, and also communicates, using isns(3), with the iSCSI name service running on other hosts to locate services and iSCSI instances. In normal operation, iscsid is a standard daemon, and will detach from the controlling terminal using daemon(3) and then loops, reading requests, processing them, and sending responses. Communication takes place over a Unix domain socket. iscsid exits on receiving a terminate message, (no response to one that is sent to the kernel), or when an error occurs reading from or writing to the socket. The -d flag increases the debug level to lvl. Any level above 0 causes iscsid to remain in the foreground, and increases the amount of debug output. The -n flag makes the daemon single-threaded. It is envisaged that user-level communication take place with iscsid using the iscsictl(8) utility, rather than directly over its communica- tion socket. An example of setting up the in-kernel iSCSI initiator is shown in iscsictl(8). SEE ALSO

iscsi -- iSCSI initiator SYNOPSIS
To compile this driver into the kernel, place the following line in the kernel configuration file: device iscsi Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): iscsi_load="YES" DESCRIPTION
The iscsi subsystem provides the kernel component of an iSCSI initiator. The initiator is the iSCSI client, which connects to an iSCSI tar- get, providing local access to a remote block device. The userland component is provided by iscsid(8) and both the kernel and userland are configured using iscsictl(8). The iscsi subsystem is responsible for implementing the "Full Feature Phase" of the iSCSI protocol. SYSCTL VARIABLES
The following variables are available as both sysctl(8) variables and loader(8) tunables: kern.iscsi.ping_timeout The number of seconds to wait for the target to respond to a NOP-Out PDU. In the event that there is no response within that time the session gets forcibly restarted. kern.iscsi.iscsid_timeout The number of seconds to wait for ctld(8) to establish a session. After that time iscsi will abort and retry. kern.iscsi.login_timeout The number of seconds to wait for a login attempt to succeed. After that time iscsi will abort and retry. kern.iscsi.maxtags The maximum number of outstanding IO requests. kern.iscsi.fail_on_disconnection Controls the behavior after an iSCSI connection has been dropped due to network problems. When set to 1, a dropped connection causes the iSCSI device nodes to be destroyed. After reconnecting, they will be created again. By default, the device nodes are left intact. While the connection is down all input/output operations are suspended, to be retried after the connection is reestablished. SEE ALSO

A solution to the mkvg failure when adding iSCSI disks to AIX.

Previous forum threads have noted that AIX cannot use iSCSI disks because it fails when trying to add them to a volume group using mkvg. The failure is caused by AIX's use of the SCSI "WRITE AND VERIFY"(0x2e) command which some iSCSI targets do not support. We experienced the same problem using... (1 Reply)
