Configure SEP sesam together with removable SATA DISK

Configure SEP sesam using removable SATA DISK Media

• SATA Disk drives can be configured as a tape drive
• To configure SEP sesam to use removable SATA DISK media follow the description below
• In this example we are using four 1TB hot plug SATA disks

Create new disk type

• Open 'Configuration-->Media Types'
• 'NEW'

• OK

Add a new drive group for the removable drives

• Go to 'Components -> Drive -> New Group -> Name: changeable_drives -> OK
• Mark the new group and click on 'New Drive'
• The sample configuration is shown in the following picture

• Switch to tab 'Options' and insert the path into the mounted media

• It is very important to create the folder sesam as the main directory on each disk

• When using Linux as your operating system, you'll find documentation below describing how to configure the auto mount function
• When using Windows insure that the operating system always use the same drive letter (X:,M:...)

Create a new media pool

• Using the GUI select 'Components -> Media Pools -> New Media Pool'
• The sample configuration is shown in the following picture

Initialise new media in the new media pool

• Insert the first disk in your server and make sure that it's already mounted to /media/satadisk
• Mark the media pool 'SATA_POOL'
• Select 'New Media' and follow the example in the picture below

• Repeat this step for the other disks

How to configure the auto mount function for Linux

Using the Unix / Linux automounter!

Assume you have configured a mount point for removable SATA media as follows:

/media/satadisk

SEP sesam requires that for each media device a folder must exist on the media selected, in this example 'sesam'. The complete path in this example the sesam saveset will be is:

/media/satadisk/sesam

To automatically mount your media you need to edit /etc/auto.master map file and add the following new entry:

/media /etc/auto.media

/media is the starting location of the /media/satadisk mount point path. For the remainder of the path, create an indirect map called /etc/auto.media with the following entry:

satadisk -fstype=ext3  :/dev/sdb1

This completes the task.

Reload the autofs service as follows:

service autofs reload

The above entries will ensure that whenever any process references the path /media/satadisk, the autofs service will automount /dev/sdb1 to /media/satadisk and ensure it is available for use.

The default timeout for a tape/sata disk dismount is 10 minutes, but this is user selectable. You can also use the sesam notify interface to issue a definitive umount command upon completion of all nightly backups.
