NetVault 12.3 - Installation Guide

Open the file sgen.conf for editing. Verify that the sgen driver is configured to attach to the target device. The “sgen” line of this file should look similar to the following:

name="sgen" parent="fp" target=0 lun=0;

Note the following:

•

Fiber Channel devices must be bound with “WWN” entries. Therefore, the “sgen” line should look something like the following example:

name="sgen" parent="fp" target=0 lun=0

fc-port-wwn="1000000cc4c8m0";

•

Editing the sgen.conf file may require that you reboot the target system.

Validate that the sgen driver has successfully created the necessary device files by:

•

Step 1: Checking to ensure that the “/devices” directory exists:

/devices/pci@7c,0/pci1022,7458@2/pci1077,1401/fp@0, 0/sgen@w1000000cc4c8m0

•

Step 2: Checking to ensure that the “/dev/scsi/changer” directory contains the appropriate files and these files have been properly associated to the target device:

/dev/scsi/changer/c2t1000000cc4c8m0d0

Create a symbolic link in the /dev directory for the NetVault Backup device file associated with the hardware path used in the /dev/scsi/changer directory:

ln -s /devices/pci@7c,0/pci1022,7458@2/pci1077, 1401/fp@0,0/sgen@w1000000cc4c8m0 /dev/nv0

Validate that the symbolic link was successfully created, and that it has the correct permissions, by issuing the following command from the prompt:

/dev/nv0 -> pci@7c,0/pci1022,7458@2/pci1077,1401/fp@0, 0/sgen@w1000000cc4c8m0,0:changer

Solaris 11 (SPARC and x86-64)

On Solaris 11, the OS does not correctly update the machine configuration to attach the library arm to the sgen driver after NetVault Backup updates the sgen.conf file. You can use the following procedure to update the machine configuration.


	NOTE: The exact steps may vary slightly depending on your machine settings. For more information, see the Oracle Solaris Administration Guide.

To correctly update the machine configuration:

Log on to the Solaris machine as root, and start a terminal session. Verify that the device is present:

cfgadm -al

Verify that the driver aliases are okay.

Create a copy of the driver_aliases file. Remove the sgen driver and install it again:


	NOTE: : You may have to copy /kernel/drv/sgen.conf to /etc/drivers/drv.

cd /etc

cp driver_aliases driver_aliases.BKP

rem_drv sgen

add_drv -m '* 0666 bin bin' -i ‘”scsiclass,08” “scsa,0.8.bmpt”’ sgen

Verify that the driver is configured:

cd /etc

grep sgen driver_aliases

If the output of the grep command shows that the aliases “scsiclass,08” and “scsa,0.8.bmpt” are assigned to the sgen driver, the driver is properly configured.

sgen "scsiclass,08"

sgen "scsa,0.8.bmpt"

Ubuntu

On Ubuntu, follow these steps to modify the startup script for NetVault Backup.

These steps are required because the /var/lock folder resides on a temporary file system on Ubuntu and gets emptied each time the operating system is shut down.

Open the file startup.sh file. You can find this file in the directory /usr/netvault/etc/.

Locate the following section in the file:

if [$OS = Linux]

then

touch /var/lock/subsys/netvault

Add line 3 to this section:

if [$OS = Linux]

then

[ -d /var/lock/subsys ] || mkdir -p /var/lock/subsys

touch /var/lock/subsys/netvault
