Bug ID: 106841
Summary: do not output error for simple subenclosure (handle
Short Enclosure Status diagnostic page)
Product: IO/Storage
Version: 2.5
Kernel Version: 4.2.4
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: SCSI
Assignee: [email protected]
Reporter: [email protected]
Regression: No
So I have the following error with a WD My Passport:
[tom@localhost ~]$ journalctl -b -p 3 | grep scsi
Oct 29 11:18:31 localhost kernel: scsi 7:0:0:1: Failed to get diagnostic page
0x8000002
Oct 29 11:18:31 localhost kernel: scsi 7:0:0:1: Failed to bind enclosure -19
Some info of the drive:
[tom@localhost ~]$ sudo sg_ses /dev/sg4
WD SES Device 1065
Supported diagnostic pages:
Supported Diagnostic Pages [sdp] [0x0]
Short Enclosure Status (SES) [ses] [0x8]
<unknown> [0x80]
<unknown> [0x83]
<unknown> [0x84]
<unknown> [0x85]
[tom@localhost ~]$ sudo sg_senddiag -P 8 /dev/sg4
Short enclosure status (SES) diagnostic page [0x8] response in hex:
00 08 00 00 00
According to SES-3 (ses3r10.pdf) Table 10, if diagnostic page 08h is supported,
all others pages from 01h to 0fh are prohibited.
However, the kernel (driver/scsi/ses.c) doesn't seem to be aware of this.
FWIW, my drive have a correct SES page (byte 0 should the page code 08h, byte
2-3 should be 0000h, byte 1 is vendor-specific status).
