The job log
reports
The
application logs show
Event
Type: Error
Event
Source: Backup Exec
Event
Category: None
Event
ID: 57665
Storage
device "BACKUP12" reported an error on a request to write data to
media.
Error
reported:
The
semaphore timeout period has expired.
Workaround
The
following workaround may correct the problem in the short term but this could
also be an indicator that the hardware is experiencing problems (depending on
how often the error occurs). It is also advised to make the following change as
a last resort to resolving the issue as this will slow down all Backup
Exec tape operations (backup, verify, restore, seeking, and so on) to a
certain degree (monitor the backup speed change after following this Technote).
The SCSI bus timeout Technote referenced below should be followed first to
provide a possible resolution as it more specifically addresses the hardware
setup and configuration.
This error
indicates that the hardware setup is at fault which is external to Backup Exec
However this device error issue can sometimes be alleviated by changing the
default value of the following registry key:
Warning:
Incorrect use of the Windows registry editor can have disastrous results
on a server operating system. Great care should be taken when making changes to
a Windows registry. Registry modifications should only be carried-out by persons
experienced in the use of the registry editor application. It is recommended
that a complete backup of the registry and workstation be made prior to making
any registry changes
HKEY_Local_Machine/Software/Symantec/Backup
Exec for Windows/Backup Exec /Engine/NTFS/FSUseAsynclO to "0"
This key
determines whether Backup Exec uses a proprietary method for accessing files (on
tape and on hard disk file systems) for both read and write functionality. A
value of 1 means Backup Exec will use the proprietary method to
accelerate such operations and a value of 0 means it will not.
OR
Open
BeUtility, right-click on the media server name, click
Edit Configuration.
By default,
File system uses asynchronous I/O will be selected. Clear this check
box
Note:
This workaround will slow down the completion time of most operations.
Therefore if/when the hardware is eventually replaced, this setting should be
changed back to default (1) once the replacement is complete.
After making
the registry change, restart the Backup Exec Device and Media Service.
