virtual tapes, and access the physical stacker directly using the virtual stacker. To
configure a physical stacker, see “Physical Stacker Device Panel” on page 84.)
Testing the Installation
Once configured for use by iSCSI initiator software on a host system, as explained earlier
in, in general, the miSAN-V-Series can be treated as any other tape device.
Virtual tape drives are normally seen by a host as IBM® 3580 LTO Ultrium tape drives,
and virtual libraries are seen as Overland™ NEO Series tape libraries. These emulations
provide for maximum compatibility with existing operating systems and backup software
applications. Using the IBM 3580 may require device drivers to be installed, which are
available from the IBM FTP site (ftp://ftp.software.ibm.com/storage/devdrvr/). Drivers for
the Overland NEO are not needed, although they are included with many backup applica-
tions. For host systems not compatible with the IBM 3580 and Overland NEO, other tape
drives and libraries can be emulated. Contact Cybernetics Technical Support
(See Appendix E “Technical Support and Repair Procedures”) regarding tape device
emulation.
After installing and configuring the miSAN-V-Series and creating virtual tapes and
devices, make sure to verify data and tape path integrity by performing a test backup and
restore over the iSCSI network. Some backup software packages include a VERIFY fea-
ture that will check to ensure the data on disk and the data on tape are identical. If the
backup software package does not include a VERIFY capability, make sure to perform a
test backup and restore operation to check the integrity of the entire data path from the
iSCSI host initiator to the miSAN-V-Series, with connected SCSI devices, and back. The
data and tape path verification process should be repeated periodically throughout the life
of the miSAN-V-Series.
Shut Down
Do not power off the miSAN-V-Series without first logging off the iSCSI initiator if applica-
ble, and shutting down the device using the Web Control Panel shut down menu.
Use this item for safely shutting down or rebooting the miSAN-V-Series. Shutting down
the HSTC engine before powering off the unit helps insure the integrity of data in the vir-
tual tape cache.
Caution
To prevent data loss before shutting down the miSAN-V-Series, make
sure all current and queued jobs have completed. To ensure no jobs are
left in the queue, wait a minimum of 30 seconds while all tape drives are
idle. Never power off the miSAN unit without first shutting down the
HSTC engine.
