(I wonder whether the "<<<additional: response too > short>>>" at the end of page 10 has something to do with the problem). Possibly ... that tends to indicate the enclosure data returned stopped in the middle of the actual specification ... although looking at the output this doesn't seem to be the case. The zeros at the end definitely indicate we have enough data, just that the expected termination doesn't seem to be present. > # sg_ses -p 0 /dev/sg17 > PROMISE 3U-SAS-16-D BP 0107 > enclosure services device > Supported diagnostic pages: > Supported diagnostic pages [0x0] > Configuration (SES) [0x1] > Enclosure status/control (SES) [0x2] > Threshold In/Out (SES) [0x5] > Enclosure busy (SES-2) [0x9] > Additional (device) element status (SES-2) [0xa] This may also be a problem. My enclosure returns page 7 as well. The traversal routine has special code to try to parse page 10 without a page 7 ... I don't think I actually ever tested that ...
