List of SCSI Diagnostic Pages
SCSI uses a one byte addressing scheme for diagnostic pages, allowing for a total 256 possible pages. There is a standard map of diagnostic page addresses shown below. Note that any given SCSI device type will only support a subset of these diagnostic pages.
Some diagnostic pages have two different meanings depending on whether they are being used for control purposes (Send Diagnostic command) or to interrogate status (Receive Diagnostic Results command). Those cases are shown as double entries in the table below using this convention: "control definition / status definition".

“Modern tourist guides have helped raised tourist expectations. And they have provided the natives—from Kaiser Wilhelm down to the villagers of Chichacestenango—with a detailed and itemized list of what is expected of them and when. These are the up-to- date scripts for actors on the tourists’ stage.”
—Daniel J. Boorstin (b. 1914)
“The way to learn German, is, to read the same dozen pages over and over a hundred times, till you know every word and particle in them, and can pronounce and repeat them by heart.”
