4 Installation Notes

Linux Installation Notes

SCSI generic module required for device support

If you are running Data Protector Express under Linux, you must install the sg (SCSI generic) module for

device suppor

t in D ata Protector Express.

To verify that this module is loaded and running, issue the following command at a terminal prompt:

lsmod

sg should be listed in the list of running modules. If it is not listed, you must manually load this mo d ule

so that Data Pr

otector Express can communicate with tape devices. Consult your operating system

documentatio

n for instructions on manually loading the sg module.

Red H at Enterprise Linux EXT3 hardware issue

If you are running Data Protector Express on Red Ha t Enterprise Linux (RHEL) v3 or v4, a known hardware

issue exists when you use the EXT3 journal or ﬁle system on certain hardware conﬁgurations. Update

your Red Hat Enterprise Linux v3 or v4 installation to the latest kernel and jbd patches listed below to

resolve this issue:

• jbd-1.1-multiarch-1

• kernel-2.6.9-11.EL (RHEL 4)

• kernel-2.4.21-37.EL (RHEL 3)

IDE/ATAPI Support

Data Prote

ctor Express supports the use of IDE/ATAPI tape devices. If your Linux d istribution compiled

the ide-tape.o module into the kernel, update the con ﬁguration ﬁ le and verify the conﬁguration to

access these devices.

NOTE:

When D ata Protector Express runs, it loads the ide-scsi module. This may cause the ide-cdrom module

to fail to l

oad, which may affect CD operation. To work around this problem, mount the CD as a SCSI

device,eventhoughitisanIDEdevice.
