HP LTO Ultrium 6 tape drives UNIX, Linux and OpenVMS configuration guide

6 Oracle (Solaris) servers and workstations

Fibre Channel drives
Before configuring your system to support an HP LTO Ultrium drive, ensure that the drive is visible
to the Oracle system HBA by correctly zoning the fabric switch (if one is being used).
Configuring the device files
Before configuring FC-attached drives, ensure the operating system is updated with the latest
recommended patches. On Solaris 9 you also need to install the Oracle/StorageTek StorEdge
SAN Foundation software from www.oracle.com/downloads(select the Storage Management link,
then StorageTek SAN x.x).
When SAN configuration is complete, verify that the drive is visible to the HBA by typing:
% cfgadm -al
This should produce an output similar to:
...
c3::50060b000xxxxxxx tape connected configured unknown
...
This indicates that the drive is configured and the device files built. In this example
c3::50060b000xxxxxxx is the attachment point identifier with 50060b000xxxxxxx being the
WWN of the drive port attached to the SAN and visible to the HBA.
If you do not see anything similar to the example above, recheck the SAN connections and the
zoning configuration to ensure that the HBA and drive ports are visible to each other.
If the tape device shows as unconfigured, type the following:
% cfgadm -c configure c3::50060b000xxxxxxx
This will build the necessary device file in the /dev/rmt directory.
To verify the particular devices associated with a specific WWN then use the following command:
% ls -al /dev/rmt | grep 50060b000xxxxxxx
Replace 50060b000xxxxxxx with the appropriate WWN for the drive.
SAS drives
Identifying attached devices
Use the cfgadm command to list attached tape devices:
% cfgadm -al |grep tape
This produces output lines with a format similar to the following:
c9::rmt/0 tape connected configured unknown
The rmt/K entry indicates the tape device file, where K is the instance number. In the above
example, rmt/0 indicates a set of device file options for one tape drive, such as /dev/rmt/0cb,
/dev/rmt/0cbn, and so on.

The cfgadm command may also be used with the –v (verbose) option to list a full path including
the SAS controller:
% cfgadm -val |grep tape
7. Device file variants for a given tape device are listed in /dev/rmt with various suffixes—l, m, h, u, c specifying the
‘density’ (low, medium, high, ultra, compressed), plus additional options b, ‘Berkeley’ behavior, and n, no rewind
behaviour. HP recommends the ‘Berkeley’ device file option for most applications with compressed density c: /dev/
rmt/0cb or /dev/rmt/0cbn
