The inquiry page data, which can be obtained by sending the -I or -I+ options, contains valuable information about the selected device. This contains everything from make and model of peripheral to more exotic information such the serial number, or maybe even where and when it was made.
The ANSI specification requires that all SCSI devices (remember SCSI includes fibre channel, SSA, and Fire Wire) have a standard inquiry page. This is the information that your operating system looks at when determining what it is hooked up to, and how it needs to communicate with it.
You can download the various ANSI specification files from http://www.t10. The documents have full information about interpreting the hundreds of bytes, bits, and bit fields found in SCSI family peripherals. In the interest of enticing you to download the spec, we will discuss a small subset of the information we are learning about one of the Seagate disk drives attached to a development system.
Please refer to this page of the specification. It shows the type of information contained in the first 36 bytes of a standard Inquiry. Note that this dump is specific to just one of many SCSI variants depending on what level of the ANSI specification your particular device supports. Various bits and bytes are first undefined, may be defined, retired (become obsolete), or changed to reflect different data depending on what level of the specification your particular device was designed to report.
If the selected disk is a SATA device, that is attached to either a SAS controller or backplane (Or your operating system or other hardware is making the device emulate a SAS device, then both the ATA and SCSI Inquiry information will report).
Notice also that the number of defects are also reported as of release 1.20. This information is not part of a standard SCSI inquiry, but it seemed like the logical place to put this type of information.
In order to obtain this information, use the -I or -I+ options ...

As you can see, the Seagate disk drive and the Tandberg tape drive have a lot of information to report. You can get part and serial numbers for individual drive components, firmware revisions, world-wide-name, and hundreds of other fields. You should also be aware that many fields are vendor-specific. This means their record layouts are not standardized by the ANSI committee, so you will need to contact Seagate to obtain this information. Please contact your manufacturer to obtain the layouts, and/or view their web sites. All of this information is usually online.
If you had just entered the -I option, you would have gotten same results, without the EVPD page hex dumps, and without the fields which appear after the defects. In the dump above, the fields in blue will only be reported with the -I+ command as they come from the EVPD pages.
Fibre Channel disk drives will also report the World Wide Name (also called the IEEE Device ID). If the above disk was a fibre channel disk, then a line such as the one below would be added to the report under Board Serial Number. This was added in release 1.30.
IEEE Unique ID: 20-00-00-11-C6-B5-64-45
Additionally, if you have an IDE disk drive and are running a distribution that supports IDE drives, you might see similar results from supplying the -I+ option:
The output below is from an SATA (ATA-7 type) drive. Each version of the ATA specification has some fields which have either been added or deleted from previous versions. In addition, some fields are specific to serial ATA (SATA) disks or parallel ATA disks (PATA), so do not expect all of these fields to be applicable to your particular type of disk drive.
