samst Driver Fails to Attach While Adding the SUNWsamfsu and SUNWsamfsr Packages

The information in this section is applicable while installing Sun QFS and Sun Storage Archive Manager 5.3 on Oracle Solaris 10 8/11 and Oracle Solaris 11 operating systems.

Installing the SUNWsamfsu and the SUNWsamfsr packages removes the media changer driver alias scsiclass,08, from an installed driver before the samst driver is added to the system. During the installation, the driver aliases file is copied to the /etc/driver_aliases.old file before any modification is made to the system. If a driver alias is removed from an existing driver, you can find the information in the /tmp/SAM_install.log file.

To use the sgen and the samst drivers with different media changer products, use the update_drv command to add the media changer by assigning the vendor ID and the product ID to the sgen driver. Do not assign a vendor ID and product ID driver alias to the samst driver. The following example shows how to add a media changer by assigning the vendor ID and the product ID to the sgen driver.

# update_drv -a -m "* 0666 root sys" -i scsiclass,08.vSTK.pL700 sgen
# devfsadm -i sgen

To use an optical disk with SAM-QFS, manually add the optical disk driver alias scsiclass,07 to the samst driver. The following example shows how to add the optical disk driver alias to the samst driver.

# update_drv -a -m "* 0666 root sys" -i scsiclass,07 samst
# devfsadm -i samst

Uninstalling the SAM-QFS software will not restore the scsiclass,08 driver alias to the previous driver. The following example shows how to restore the media changer driver alias to the sgen driver after the SUNWsamfsu and the SUNWsamfsr packages are uninstalled.

# update_drv -a -m "* 0666 root sys" -i scsiclass,08 sgen
# devfsadm -i sgen

Media Changer Catalog

The media changer catalog has been changed for this release and is not compatible with the previous releases. SAM-QFS will automatically upgrade the catalog when migrating from SAM-QFS 5.2 to SAM-QFS 5.3 without any input from the system administrator. The SAM-QFS 5.3 backto command converts all media changer catalogs and the historian from the SAM-QFS 5.3 version to the SAM-QFS 4.1 version, which is suitable for any SAM-QFS 5.2 release. If you fail to run the SAM-QFS 5.3 backto command, your media changer catalogs and the historian file will show a .bad file extension after you run the samd start command for the first time.

To recover the 5.3 catalogs and historian:

1. Reinstall the SAM-QFS 5.3 software.

2. Move the .bad media changer catalogs and the historian back to the original file name as listed in your mcf file.

3. Run the backto command.

4. Uninstall the SAM-QFS 5.3 software.

5. Install the SAM-QFS 5.2 software.

For more information about installing and uninstalling the SAM-QFS software, see Sun QFS and Sun Storage Archive Manager 5.3 Installation Guide.
