Creating Attach Points with makedev
Installing Oracle Secure Backup on Linux or UNIX 2-19
driver that is included with Solaris now provides the functionality provided by the
kernel driver.
Enabling the Solaris sgen Driver for Changer and Sequential Devices
You need to enable the Solaris sgen driver for changer and sequential devices before
you install Oracle Secure Backup.
Use the following steps to enable the Solaris sgen driver for sequential and changer
devices:
1. If your host does not have a previous installation of Oracle Secure Backup, skip to
Step 2.
When you enable the Solaris sgen driver on a host that already has Oracle Secure
Backup installed, the attach points and device configuration will be lost. You need
to first uninstall Oracle Secure Backup using the steps described in "Uninstalling
Oracle Secure Backup on Linux or UNIX" on page 2-20.
While uninstalling, it is recommended that you remove the backup directory. You
can retain that admin directory.
2. Enable sequential (01) and changer (01) devices by adding the following line in the
/kernel/drv/sgen.conf file:
device-type-config-list="sequential","changer";
3. Verify that there is an entry for the sgen driver in /etc/minor_perm.
An example of an entry in this file is as follows:
"sgen * 0600 root sys"
4. Verify that there is an entry for the sgen driver in /etc/name_to_major.
The following is an example of an entry in this file:
"sgen 151"
5. Remove the links in /dev/scsi/changer and /dev/scsi/sequential using
the following commands:
rm -r /dev/scsi/changer
rm -r /dev/scsi/sequential
6. Unconfigure the st driver for type 01 devices using the following command:
update_drv -d -i '"scsiclass,01"' st
7. Configure sgen driver for the types 01 and 08 using the following command:
add_drv -m '*0666 bin bin' -i '"scsiclass,01" "scsiclass,08" "scsa,01.bmpt"
"scsa,0.8.bmpt"' sgen
After you complete the steps to enable the sgen driver, there must be entries in
/etc/scsi/changer for every library and /etc/scsi/sequential for every tape
Note: If device-type-config-list is already defined for other
devices, add "sequential" and "changer" to the existing list in the
sgen.conf file.
