LUN cloning allows the user to create a copy of a LUN, which was initially created to be backed by a LUN or a file in a snapshot (i.e. using lun clone create ). LUN cloning creates a complete copy of the LUN and frees the snapshot, which can then be deleted. The lun clone create command creates a lun on the local filer that is a clone of a "backing" lun. A clone is a lun that is a writable snapshot of another lun. Initially, the clone and its parent share the same storage; more storage space is consumed only as one lun or the other changes. The parent_snap is locked in the parent volume, preventing its deletion until the clone is either destroyed or split from the parent using the lun clone split start command. The lun clone create command fails if the chosen parent_lunpath is currently involved in a lun clone split operation. lun clone split start lun_path This command begins separating clone lun_path from its underlying parent. New storage is allocated ...

Persistent Name Binding support is available for target devices. This support is provided for users to associate a specified device World Wide Port Name (WWPN) to a specified SCSI target ID. For driver version earlier than 4.15, it is implemented through both the /kernel/drv/sd.conf and /kernel/drv/qla2300.conf files. The matching between the target device port, the SCSI target ID, and the adapter driver instance happens inside /kernel/drv/qla2300.conf. For driver versions 4.15 and later, the driver dynamically discovers targets, so no entries in the sd.conf or st.conf files are required. Note that if you disable dynamic discovery of devices (via the hbaX-disable-dynamic-device-support parameter), you must populate the sd.conf and st.conf files as noted above for pre-4.15 drivers. The Persistent Name Binding support for target devices associates a SCSI target ID to a specified device World Wide Port Name or port ID. If port ID binding is specified it takes precedent over World Wi...

World Wide Name (WWN) are unique 8 byte (64-bit) identifiers in SCSI or fibre channel similar to that of MAC Addresses on a Network Interface Card (NIC). Talking about the WWN names, there are also World Wide port Name (WWpN), a WWN assigned to a port on a Fabric which is what you would be looking for most of the time. World Wide node Name (WWnN), a WWN assigned to a node/device on a Fibre Channel fabric. To find the WWN numbers of your HBA card in Sun Solaris, you can use one the following procedures Using fcinfo (Solaris 10 only) This is probably the easiest way to find the WWN numbers on your HBA card. Here you can see the HBA Port WWN (WWpN) and the Node WWN (WWnN) of the two ports on the installed Qlogic HAB card. This is also useful in finding the Model number, Firmwar version FCode, supported and current speeds and the port status of the HBA card/port. root@ sunserver:/root# fcinfo hba-port grep WWN root@ sunserver:/root# scli -i egrep “Node NamePort Name” root@...
