Solution Type Technical Instruction Sure Solution 1001713.1 : Sun StorEdge[TM] 6900:How to Map VLUN Serial Number to a specific c#t#d# device
PreviouslyPublishedAs 202330 Description This document will explain how to map a VLUN serial number to a specific c#t#d# device on a Sun StorEdge[TM] 6900. Steps to Follow On the Sun StorEdge[TM] 6900 SP, you must run the following command to get the VLUN Serial Number, which is a unique identifier for the Sun StorEdge[TM] T3 lun-slices that are presented to the host via the virtualization engine.

The VLUN serial number is 6257357430303570. On systems with MPxIO enabled, it is simple to identify the VLUN as the target value in the c#t#d# is the Virtualization Engine's UID concatenated with the VLUN's serial number: (c#tUID+SerialNumberd#) c11t29000060220042256257357430303570d0 On systems with MPxIO disabled, it will be more difficult to determine. All the VLUNs will appear as c#tWWNd#. The WWN value is the WWN of the Virtualization Engine. Use the method below to determine the correct device. # /usr/sbin/format -e -> select one of the devices with the appropriate WWN, in this example we will use c11t2b00006022004225d9 -> then select scsi -> then select inquiry scsi> inquiry Inquiry: 00 00 03 12 2b 00 00 02 53 55 4e 20 20 20 20 20 ....+...SUN 53 45 53 53 30 31 20 20 20 20 20 20 20 20 20 20 SESS01 30 38 31 32 62 57 35 74 30 30 35 70 30 30 30 0812bW5t005p000 Vendor: SUN Product: SESS01 Revision: 0812 Removable media: no Device type: 0 ISO version: 0 ECMA version: 0 ANSI version: 3 Async event notification: no Terminate i/o process msg: no Response data format: 2 Additional length: 43 Relative addressing: no 32 bit transfers: no 16 bit transfers: no Synchronous transfers: no Linked commands: no Command queueing: yes Soft reset option: no The following number is taken from the byte data at the top of the inquiry output. The 3rd row starting from the 5th byte and ending at the 12th byte: 62 57 35 74 30 30 35 70 This is the VLUN Serial number for the c#t#d# selected. As we can see from the showvemap, the device c11t2b00006022004225d9 maps to the VLUN serial number of 6257357430303570. If the serial number doesn't match, then select another device with the above method until a match is found.
