Übersicht

This article describes how to restore the SEP sesam Server from tape via sbc without using sm_recover. For details on SBC CLI usage and available commands, see SBC CLI.

Prerequisites

  • Operating system with working tape drive or loader device.
  • Installed SEP sesam Server (identical version to the preceding system): Install the same SEP sesam Server package that was installed on the old system and set up the new server system in the same way as the previous one. For details on installation, see SEP sesam Quick Install Guide.
  • A medium that contains correctly saved SESAM_BACKUP (containing <SESAM_VAR> and <SESAM_ROOT>/bin/sesam directories). For details, see Configuring SESAM_BACKUP.

Restore procedure

The restore of the SEP sesam Server described below is a two-step procedure consisting of determining the required saveset information and restoring via sbc.

Listing the savesets on the tape via sm_sms_interface

Use the sm_sms_interface command to access the SMS Server and identify the available savesets on tape.

  1. Insert the tape with the SESAM_BACKUP backup savesets and identify the savesets on the tape device by using the command:
  2. sm_sms_interface dir -d <tape_device>

    On Windows, replace the tape device identifier (/dev/nst0) with the corresponding Windows device (Tape0).

    Obtain the required information from the output as shown in the example below:

    • The first number in the highlighted line is the segment number; in our example: 4.
    • The SavesetName is SEP sesam unique identification assigned to a saveset; in our example: SC20090610105624.
    • The Tapelabel in the header displays the <tape_name>; in our example: cefix00001.
    • The TapeID in the header displays the <tape_id>; in our example: (1)

    Restoring from tape via sbc

  3. Restore the saveset by using the following sbc command:
  4. sbc -r -l FULL -C <control_host>:11001 -S <storage_host>:11001 -d SMS:<tape_device> -t <tape_name>:<tape_id> -s <saveset_id> -n <segment_number> -R / -o overwrite
    
    Information sign.png Note
    • In our example, the command overwrites the existing data files (-o overwrite)! Make sure to remove the overwrite option if you do not want to overwrite the files.
    • You can change the restore target by specifying -R <restore_target>.
    • <control_host> is the name of the SEP sesam Server.
    • <storage_host> is the SEP sesam Server or Remote Device Server (RDS) with the attached medium.
