This section explains about the settings to be done after restoring the system disk.
When using the shared class or local class of GDS, perform the following settings regardless of whether the system disk is mirrored by GDS.
Note
After restoring the system disk, perform the following settings before starting up the system in multi-user mode.
[Setting procedure]
1) If "7.4.1 Settings Before Backing Up" is not executed, start up the system in single-user mode and set according to "7.4.1 Settings Before Backing Up."
In case of the following, this setting is not necessary.
When set according to "7.4.1 Settings Before Backing Up"
When not using shared class and local class
2) Start up the system in multi-user mode.
3) Check if there are no errors in the configuration and state of the shared and local classes.
# sdxinfo |
4) Restore the configuration of mirroring among servers.
This procedure is performed only when using the mirroring among servers function.
4-1) Delete the iSCSI device information used in mirroring among servers.
This procedure is performed when restoring after stopping all the nodes.
When restoring in another node while the service continues in the operating node, this procedure must not be performed.
Execute the following commands on all the nodes.
# rm -f /var/opt/FJSVsdx/log/.sdxnetmirror_disable.db |
4-2) Restore the slice status of netmirror volume.
This procedure is performed when restoring after stopping all the nodes.
When restoring in another node while the service continues in the operating node, this procedure must not be performed.
Execute the following command on any node for all the netmirror volume.
Check the status of the copy source slice for the synchronization copying when both nodes are stopped before restoring.
Restore the status of the slice using sdxfix command when the copy source slice for the synchronization copying is INVALID.
For the -d option of sdxfix command, specify the copy source disk for the synchronization copying.
Example) When the class name is class0001, the volume name is volume0002, and the disk name is disk0001.
# sdxfix -V -c class0001 -v volume0002 -d disk0001 -x NoRdchk |
4-3) Undo the automatic startup setting of RMS.
If the automatic startup setting of RMS is changed in step 1) or "7.4.1 Settings Before Backing Up," set the automatic startup of RMS.
# hvsetenv HV_RCSTART 1 |
4-4) Start up RMS.
5) Undo the configuration parameter settings of GDS.
Comment out the line of SDX_DB_FAIL_NUM=0 in the /etc/opt/FJSVsdx/sdx.cf configuration file.
# vim /etc/opt/FJSVsdx/sdx.cf |
