Manage host initiators

After you create a host configuration for controlling host access to storage on the system, you need to create one or more initiators for each host configuration that accesses the storage system. Each initiator represents the initiator on the host, which will connect to the storage system. There are two types of initiators, Fibre Channel (FC) and iSCSI.

A FC initiator contains the WWN of an HBA on the host. This WWN is not the WWN of the host.

An iSCSI initiator contains the IQN (iSCSI Qualified Name) used by the host, and optionally the CHAP authentication password associated with the host. Manage reverse CHAP for mutual CHAP authentication explains how to configure reverse (two-way) CHAP authentication on the system.

Each initiator is identified by an ID.

The following table lists the attributes for initiators.

Table 1. Initiator attributes
Attribute Description
ID Host initiator ID.
Host Name of the parent host.
UID FC WWN or iSCSI IQN of the initiator.
Initiator type The type of initiator. Value is one of the following:
  • FC
  • iSCSI
Ports logged in Comma-separated list of array target ports that the initiator is logged into.
Ignored Indicates whether the initiator is ignored for data access to the host. Value is one of the following:
  • Yes — The initiator is ignored.
  • No — The initiator is not ignored.
Health state Health state of the system. The health state code appears in parentheses. Value is one of the following:
  • Unknown (0) — Status is unknown.
  • OK (5) — Working correctly.
  • OK BUT (7) — Working correctly, but there could be a problem.
  • Degraded/Warning (10) — Working and performing all functions, but the performance may not be optimum.
  • Minor failure (15) — Working and performing all functions but overall performance is degraded. This condition has a minor impact on the system and should be remedied at some point, but does not have to be fixed immediately.
  • Major failure (20) — Failing and some or all functions may be degraded or not working. This condition has a significant impact on the system and should be remedied immediately.
  • Critical failure (25) — Failed and recovery may not be possible. This condition has resulted in data loss and should be remedied immediately.
  • Non-recoverable error (30) — Completely failed and cannot be recovered.
Health details Additional health information. See Appendix A, Reference, for health information details.
CHAP users List of CHAP accounts configured for the initiator.
Source type The source initiator type. Values are:
  • HPAutotrespass - HP with Auto-trespass
  • OpenNative (default) - Open native (such as CLARiiON Open)
  • SGI - Silicon Graphics
  • HPNoAutotrespass- HP without Auto-trespass
  • Dell
  • FujitsuSiemens
  • Tru64- Compaq Tru64
Failover mode The failover mode for the initiator. Values are:
  • AutoTrespass- Any media access to the non owning SP is rejected.
  • PassiveNotReady- A command failure during I/O is sent to the non-owning SP.
  • DMP- Quiet trespass on I/O to non owning SP.
  • PassiveAlwaysReady- Some commands, e.g. Test Unit Ready, returns PAR status.
  • ALUA(default) - Initiators are permitted to send I/O to a LUN regardless of which SP actually owns the LUN.
LUNZ enabled Specifies whether LUNZ is enabled. Values are:
  • yes (default)
  • no
Unit serial number Indicates the unity serial number. Values are:
  • Array (default)
  • LUN

For SCSI-3 interfaces, the Unity Serial Number page (Vital Product Data page 0x80) reports the serial number for the array or LUN.
