Figure 46 Redundant SAS Data Paths Are Present
Using CmdTool2 to Verify Dual-Ported SAS Addresses to Disk Drives
The CmdTool2 configuration display command (-cfgdsply) returns many lines of information, including a
summary for each physical disk. To confirm the controller discovery of both SAS addresses for a single
drive, examine the CmdTool2 configuration text for the drive information following the Physical Disk
line. Following is the CmdTool2 configuration display command followed by a portion of the information
presented for each physical drive, up to the lines that show the drive's SAS addresses. If only one of the
drive's SAS ports was discovered, the second SAS address is listed as 0x0. If both drive SAS ports were
discovered, the second drive port SAS address is identical to the first except for the last hexadecimal digit,
which always has a value of plus or minus 1 relative to SAS Address(0).
The syntax of the CmdTool2 command is as follows:
CmdTool2 –cfgdsply –a0
The returned information relating to the physical disk is as follows. Some of the other preceding text is
removed for brevity. The dual SAS addresses are listed at the end.
Physical Disk: 0
Enclosure Device ID: 65
Slot Number: 1
Drive's postion: DiskGroup: 0, Span: 0, Arm: 0
Enclosure position: 0
