(Command Lines)

This option allows the user to disable support of wide SCSI when using a wide SCSI
controller. Set this option to “disable” if a wide SCSI device is present on the sys-
tem, but a narrow SCSI cable is connected somewhere on the bus between the wide
SCSI host adapter and the wide device, thus prohibiting the transfer of wide data. If
this option is set to “disable”, the wide device still works, but all data transferred to/
from the device is narrow (8 bit). The driver does not initiate a wide SCSI transfer
request negotiation.

Using the Number of Error Recovery Retries Option
Command line option: max_retry=

Valid options:

0-50

Function:

Set the maximum limit on the number of times to retry an IO
on a non-sequential access device in the event of a SCSI
error condition.

Possible Impact:

Setting this to 0 prevents the driver from retrying an IO in
the event of an error.

If SCSI error conditions occur on a non-sequential access device, the driver retries
an IO operation the set number of times before giving up and returning the IO to the
caller with a failed status. Possible callers are NetWare or an application via the
CAM or ASPI interface. If this option is set to 0, IOs are not retried in the event of
an error condition.

NOTE: Some SCSI error conditions (such as DATA PROTECT or ILLEGAL
REQUEST) do not warrant a retry. Such conditions are reported but not re-
tried, even for positive values of max_retry.

Using the Logging of SCSI Errors Option
Command line option: Log_ScsiErrors=

Both

Valid options:

Off/Console/Syslog/Both

Function:

Specify where to log serious SCSI errors.

Possible Impact:

Changing this option may result in loss of this information.

If SCSI error conditions occur, the driver normally attempts to log a SCSI Error
Report describing the event to both the console and the system log file
SYS:SYSTEM\SYS$LOG.ERR. This information is valuable in determining when
a device is having problems. It can indicate when a device is beginning to fail,
providing an opportunity to replace the device before complete failure.

With this option you can choose to specify where these messages are logged: Con-
sole - the server console only; Syslog - the system error log; Both - both the server
console and the system error log; or Off - the error messages are not logged any-
where.

NOTE: This option affects the logging of serious SCSI errors only. Non-SCSI
errors are still logged to both the console and system error log.
