4.8.2 Checking and Setting Required Packages

Set the following configuration for all nodes in which the mirroring function among servers is used.

The setting procedures are different depending on OS version.

[RHEL6]

1. Check that the scsi-target-utils package and the sg3_utils package are installed.

   # rpm -q scsi-target-utils
   scsi-target-utils-xxxxxxxx
   # rpm -q sg3_utils
   sg3_utils-xxxxxxxx

   If the package is not installed, install the package from an installation CD for OS of the target system.
   

2. Check that the iscsi-initiator-utils package is installed.

   # rpm -q iscsi-initiator-utils
   iscsi-initiator-utils-xxxxxxxx

   If the package is not installed, install the package from an installation CD for OS of the target system.
   

3. Change the setting of the stop order for the SCSI target daemon (tgtd).

   # vim /etc/init.d/tgtd

   [Before change]

   #!/bin/sh
   #
   # chkconfig: - 39 35
   ...

   [After change]

   #!/bin/sh
   #
   # chkconfig: - 39 90
   ...

4. Register the SCSI target daemon (tgtd) again.

   # chkconfig --del tgtd
   # chkconfig --add tgtd

5. Set to automatically start the SCSI target daemon (tgtd) when the system is started.

   # chkconfig tgtd on

Note

If the scsi-target-utils package was upgraded by using kernel upgrade or errata, it is necessary to repeat procedures 3 to 5.

[RHEL7]

1. Check that the targetcli package has already been installed.

   # rpm -q targetcli

2. Set the start and stop order for iSCSI target service.

   Create the directory, /etc/systemd/system/fjsvsdx.service.d.

   # mkdir /etc/systemd/system/fjsvsdx.service.d
   # chmod 755 /etc/systemd/system/fjsvsdx.service.d

   Create the setting file within the created directory.

   # touch /etc/systemd/system/fjsvsdx.service.d/netmirror.conf
   # chmod 644 /etc/systemd/system/fjsvsdx.service.d/netmirror.conf

   Add the following content to the setting file.

   [Unit]
   After=target.service

   Apply the setting of the start and stop order for iSCSI target service.

   # systemctl daemon-reload

3. Check the setting of the start and stop order for iSCSI target service.

   # systemctl show fjsvsdx.service | grep "After="
   After=iscsi-shutdown.service iscsi.service target.service ...

   Confirm that target.service is output.

4. Set to automatically start the iSCSI target service when the system is started.

   # systemctl enable target.service
