Backup and Restore The file restore.log is used to record recovery activities. It is in the root directory of the DSPERU diskette. Please note that this diskette, and therefore the log is only readable on a UNIX system. The first line of the log, contains the time and date the recovery was initiated. To prevent the log from being overwritten the next time a recovery is performed, rename the log. You should give it a name that is somehow related the date that the recovery was made (for example, restore040402.log). Checking the tape drive If the backup or recovery script generates an error message indicating that the tape drive cannot be found, perform the following steps: 1. If DocuSP is running, follow the procedures in your customer documentation to shut down and power off the controller. If the system displays a # prompt, enter halt. When the OK prompt is displayed, power off the controller. 2. Power off the tape drive. 3. Ensure that the SCSI cable connecting the tape drive to the controller is securely connected. If the tape drive is your systems only external SCSI device, there should be only one SCSI cable connected to the tape drive, and it should be connected to the In connector. If there are other SCSI devices (for example, external hard drives), ensure that the cable connected to the In connector leads back towards the controller (even if there is another device between the tape drive and the controller). Also verify that there are no bent pins on the connector. 1. If the tape drive is an older unit (for example, an 8mm DocuTech tape drive) with a 50-pin SCSI connector, a terminator must be installed on the Out connector if the tape drive is the last device on the SCSI chain. NOTE: The 50-pin connector is approximately 1.5 inches wide. Newer tape devices have a 68-pin Ultra-SCSI connector, which is 1.75 inches wide. NOTE: The 4mm and QIC tape drives are all Ultra-SCSI devices. These are auto-terminating so no external terminator is needed. System Guide 2-15

Backup and Restore
System Guide
2-15
The file
restore.log
is used to record recovery activities. It is
in the root directory of the DSPERU diskette. Please note that
this diskette, and therefore the log is only readable on a UNIX
system. The first line of the log, contains the time and date
the recovery was initiated. To prevent the log from being
overwritten the next time a recovery is performed, rename
the log.
You should give it a name that is somehow related
the date that the recovery was made (for example,
restore040402.log
).
Checking the tape drive
If the backup or recovery script generates an error message
indicating that the tape drive cannot be found, perform the
following steps:
1.
If DocuSP is running, follow the procedures in your
customer documentation to shut down and power off the
controller. If the system displays a # prompt, enter
halt
.
When the OK prompt is displayed, power off the
controller.
2.
Power off the tape drive.
3.
Ensure that the SCSI cable connecting the tape drive to
the controller is securely connected. If the tape drive is
your systems only external SCSI device, there should be
only one SCSI cable connected to the tape drive, and it
should be connected to the
In
connector.
If there are other SCSI devices (for example, external hard
drives), ensure that the cable connected to the In connector
leads back towards the controller (even if there is another
device between the tape drive and the controller). Also verify
that there are no bent pins on the connector.
1.
If the tape drive is an older unit (for example, an 8mm
DocuTech tape drive) with a 50-pin SCSI connector, a
terminator must be installed on the
Out
connector if the
tape drive is the last device on the SCSI chain.
NOTE:
The 50-pin connector is approximately 1.5 inches
wide. Newer tape devices have a 68-pin Ultra-SCSI
connector, which is 1.75 inches wide.
NOTE:
The 4mm and QIC tape drives are all Ultra-SCSI
devices. These are auto-terminating so no external
terminator is needed.
