When the system can be safely brought down, boot from the media into
the main menu.
Select Utilities -> Archive Utilities -> Test Archive Media
and read from the backup for a few minutes, just to make sure
everything is OK.
If you plan on doing remote crash recovery, enable modem or network
support and use another machine to dial or telnet in and test this
capability. List files from a remote backup if that feature will be used.
Constructing Boot Strings
Whenever you are booting and need to use a BTLD, you must tell the
boot command...
• the directory name of the BTLD on the BTLD diskette.
• the actual BTLD driver name.
• The devices (typically hard drives and tape drive) that are
attached to the host adapter controlled by the BTLD driver.
This is done by constructing a boot command listing the appropriate
directives. Consider the following command syntax:
defbootstr link=XXXXX Sdsk=YYYYY(0,[0,]0,0) Stp=YYYYY(0,[0,]0,0)
| | | | | |
Btld Name---+ | | | | +--Lun Number
| | | +----SCSI ID
Actual Driver Name-------+ | +-------Optional Bus Number
+----------Drive Number
where defbootstr means to use the current default boot string, XXXXX
is the on-disk directory name of the BTLD you are trying to load, YYYYY
is the actual driver to be installed, and the zeros should be replaced
with appropriate values for your hardware configuration (at minimum
the SCSI ID for the tape drive (Stp) must be different from the SCSI ID
for the hard drive (Sdsk)).
Bus numbers are rarely used, so they can usually be ignored, leaving...
defbootstr link=XXXXX Sdsk=YYYYY(0,0,0) Stp=YYYYY(0,0,0)
| | | | |
Btld Name-----+ | | | +--Lun Number
| | +----SCSI ID
Actual Driver Name---------+ +------Drive Number
The on-disk directory name (Btld Name) and the Actual Driver Name
are usually identical. This is true for all drivers downloaded from the
Xinuos web site.
However, the Adaptec web site has BTLD diskettes with drivers for
multiple operating systems on them. On their latest driver diskette, the
OpenServer 5 driver is located in the blad325 directory, while the
driver itself is called blad. In this special case, XXXXX would be
blad325, while YYYYY would be blad.
As an example, suppose we wanted to construct a command to link the
Adaptec 29160 driver (ad160) from the driver diskette image on the
Xinuos ftp site, with the primary hard disk on SCSI ID 0 and the tape
drive on SCSI ID 2. In this instance the disk name and the driver name
are identical, so the command would look like this...
defbootstr link=ad160 Sdsk=ad160(0,0,0) Stp=ad160(0,2,0)
