  • Page 114: Introduction To Volume Exposure & Security

    Both iSCSI initiators and targets have a World Wide Unique Identifier (WWUI) of up to 256 free form characters, e.g. www.sanrad.vswitch1.target1. You create a V-Switch target by assigning an alias and WWUI to it. You assign a Logical Unit Number (LUN) to a volume and then attach the LUN to an iSCSI target to expose the volume to hosts.

  • Page 115: Identities

    Identities To allow selective iSCSI initiator access to iSCSI target volumes, the V- Switch uses identities to define pools of initiators. An identity is a user- defined list of iSCSI initiators. An identity can contain from one to multiple initiators, with each initiator having a unique WWUI.
  • Page 116 Ident B wwui6 wwui7 wwui8 wwui9 wwui10 Figure 55. Identity B’s iSCSI Initiators wwui1 wwui2 Ident A wwui3 wwui4 wwui5 Ident B Ident B wwui6 wwui7 wwui8 Ident C wwui9 wwui10 Figure 56. Identity C’s iSCSI Initiator SANRAD V-Switch User Manual...

  • Page 117: Access Rights

    An identity can be used with more than one target. In Figure 57, Identity A is coupled with both Targets 1 and 2. Identity B is coupled with Target 3. Identity C is coupled with Target 4. As a result, each iSCSI initiator has access to the following volumes: SCSI I NITIATOR...
  • Page 118 When you assign an identity to a target, you give the identity a position, beginning with 1 and increasing in number with increasing specificity of the identity. A position is an identity’s rank in the V-Switch scan for an iSCSI initiator – identity match. When the V-Switch scans the list of identities coupled with a target, it starts with the highest position and stops with the first iSCSI initiator –...

  • Page 119: Authentication

    If Identity A is assigned position 1 and Identity B is assigned position 2, Identity B is scanned first by the V-Switch. A match is made and the scan is stopped. No further identities will be scanned. Therefore, iSCSI initiator WWUI8 will be granted read-write access.
  • Page 120 (NA) for all initiators. Remember that the default identity is in position 0 so it is the last position scanned by the V-Switch. Target 1 is coupled with Identity A with read-write (RW) access to Identity A iSCSI initiators, meaning WWUI1.

  • Page 121: Creating An Iscsi Target

    If iSCSI initiator WWUI1 tries to login to Target 2, the V-Switch first scans Identity B. It does not find the initiator listed so it continues to scan the next identity, the default identity. The default identity blocks all iSCSI initiators, including WWUI1.

    Exporting a Corrupted Database After you reboot the V-Switch from safe mode level 1 or 2, you can use the CLI command ft export problem to export the potentially corrupted database to SANRAD technical support for examination. If you rebooted in safe mode level 1 (last good configuration), the last good database file and the corrupted database file are exported for examination.
