Solution 1007692.1 : Sun Storage 3510 and 3511 Arrays: How to Identify Switch IDs, Disk IDs and Correct Backend Cabling

Applies to:

Sun Storage 3510 FC Array - Version Not Applicable and later
Sun Storage 3511 SATA Array - Version Not Applicable and later
All Platforms

Goal

This document describes how to identify the disk IDs when the ID Selection Switch of the Sun Storage 3510 and 3511 Arrays are set to numbers 0-7. It also explains how to identify the cabling schemes for these devices.

Solution

For more information about the loop IDs of disks in the expansion units of the 3510 and 3511, refer to Section 4.6 of the Sun StorEdge 3000 Family Installation, Operation, and Service Manual. The tables below provides the details about Loop ID of each disk in 8 expansion units, which is the maximum supported configuration.

Chassis ID Switch	Disk ID Range
0	0-15
1	16-31
2	32-47
3	48-63
4	64-79
5	80-95
6	96-111
7	112-125

50   53   56   59   (SES Loop ID is 60)

Target Disk drive(s) Loop IDs are 64-75 (ID Switch is set to 4;Chassis ID 4)
64   67   70   73
65   68   71   74
66   69   72   75   (SES Loop ID is 76)

Target Disk drive(s) Loop IDs are 80-91 (ID Switch is set to 5;Chassis ID 5)
80   83   86   89
81   84   87   90
82   85   88   91   (SES Loop ID is 92)

Target Disk drive(s) Loop IDs are 96-107 (ID Switch is set to 6;Chassis ID 6)
96   99   102   105
97   100   103   106
98   101   104   107   (SES Loop ID is 108)

Target Disk drive(s) Loop IDs are 112-123 (ID Switch is set to 7;Chassis ID 7)
112   115   118   121
113   116   119   122
114   117   120   123   (SES Loop ID is 124)

The recommended cabling configuration and the steps to connect expansion units are given in Section 4.5 of the Sun StorEdge 3000 Family Installation, Operation, and Service Manual. The cabling diagrams to connect the maximum of 8 expansion units are given on pages 43-56 of the Sun StorEdge 3000 Family Best Practices Manual.
