(see “Menu Structure (5 of 5—Log Pages)” on page 3-10).
These selections provide access to drive error information contained in SCSI
log pages. Three menus in this category (
(5525 &2817(56 '5,9(
(55256, and '5,9( )$,/85(6) give access to “pages” of SCSI log entries.
Three additional items (
(1$%/( /2* 5(6(7 /2*, and 6(7
7+5(6+2/'6) are commands that allow you to manipulate or control these
internal log pages. These commands affect all log pages and cannot be applied
deferentially to individual log pages.
ERROR
COUNTERS
For each drive, this menu gives access to a tally of recovered errors and a tally
of medium errors. Medium errors are non-recoverable errors related to flaws
in the drive’s memory medium material. The
(5525 &2817(56 menu item
relates to SCSI log page number 3.
DRV n ERR COUNT / RECOVERED
Displays a 5-digit tally of recovered errors for each drive (with a maximum
tally of 65,535 errors). “n” is the drive number (n=1-9).
DRV n ERR COUNT / MEDIUM
Displays a 5-digit tally of medium errors for each drive (with a maximum tally
of 65,535 errors). “n” is the drive number (n=1-9).
DRIVE
ERRORS
This item gives access to the error entry for each recorded drive error
occurrence. 40 error entries can be stored. For each error occurrence, an error
entry number is assigned. The error entry identifies the drive on which the error
occurred, gives SCSI codes that describe the error, and tells the location on the
drive (logical block address) at which the error occurred, if applicable.
The sense key code gives the primary description of the error. ASC and ASQ
codes give additional information about the error entry, but for some error
entries, these two codes will not be applicable. Because the 6500 arrays are
equipped with ATA drives, they produce ATA error codes. These are
translated, on the controller board, into SCSI codes to maintain compatibility
with arrays equipped with SCSI drives. The
'5,9( (55256 item relates to
SCSI log page number 4.
If no errors have been recorded, the display for this menu item will read
'5,9(
(55256 /,67 (037<.
ENTRY k / DRIVE n
This item gives you access to error entries by entry number and tells you the
drive on which each error occurred (k=1-40, n=1-9).
