5.5 Backup and restore of the management partition information

The following sections explain backup and restore of management partition.

1. Backup of management partition information

Use sfcgetconf(8) command to make a backup of the management partition information.

# sfcgetconf _backup_file_

For details on sfcgetconf(8), see sfcgetconf(8) in this manual.

Make a backup of the management partition information when changing the configuration of the file system with such commands as sfcmkfs(8), sfcadm(8), and sfcnode(8).

sfcgetconf(8) generate a shell script named _backup_file_:

# cat _backup_file_
#!/bin/sh
# This file is made by:
#    sfcgetconf _backup_file_
# Tue Jun 18 09:08:06 2002
#---- fsid : 1 ----
# MDS primary   (port) : host1 (sfcfs-1)
# MDS secondary (port) : host2 (sfcfs-1)
# MDS other            :
# AC      : host1,host2
# options :
# device  : /dev/sfdsk/c1/dsk/v1
sfcadm -m host1,host2 -g host1,hostw -p sfcfs-1,sfcfs-1 /dev/sfdsk/c1/dsk/v1
...

To make a backup of management partition information by sfcgetconf(8), the file system monitoring mechanism needs to run on the cluster. If file system monitoring mechanism has not run, please start by sfcfrmstart(8).

2. Setting up the new management partition and starting the file system monitoring mechanism

If a management partition is broken, then set up a new management partition on GDS volume and start the file system monitoring mechanism.

For the details of management partition setting and the file system monitoring mechanism starting, refer to "Configuring the Management Partition and Starting the File System Monitoring Mechanism".

3. Restoration of management partition information

Shell script generated by sfcgetconf(8) in the procedure described in " Backup of management partition information" is used for the restoration of management partition information.

The method of restoration of the management partition information is explained below.

# sh _backup_file_
get other node information start ... end
