Cisco UCS Invicta Scaling System Administration and Configuration Guide, Version 5.0.1.1a
Chapter 5 Asynchronous Replication
Note When using Async Replication for Non-Cisco Pairing types (i.e., Windows, Linux-LVM, and
Linux-Raw), the mounting the Destination LUN any initiator for the purposes of viewing the data is not
supported. The ability to mount the Destination LUN is supported only when a Cisco-partner type is used
and the Destination entity resides on a Cisco UCS Invicta Appliance or Cisco UCS Invicta Scaling
System.
Note The Target device the format is /dev/<VG name>/<destination entity>.
Cisco to Cisco
Cisco-to-Cisco Async Replication is preconfigured and is complete. To create a pairing, see “Create a
Pairing, page 5-7.”
Cisco to Linux-LVM
Step 1 Click Public Key to obtain the public key necessary for using password-less ssh access.
The SSH Public Key dialog box appears.
Step 2 Copy the ssh key and click OK.
Step 3 Open a Terminal window and navigate to the /root/.ssh directory.
Step 4 Enter vi authorized_keys.
Step 5 Paste the Cisco Public Key copied in Step 2 into the authorized_keys list and click Enter.
See the following sample
procedure to configure a Linux Host to be used as a Linux ‘Open Target’
partner for Async Replication.
Sample Procedure:
Note This example uses CentOS 6.2
You need the following:
• LVM 2.0.2:
yum –y install lvm2
• Install Openssh server and clients:
yum -y install openssh-server openssh-clients
• Add and start sshd service daemon:
– chkconfig sshd on
– service sshd start
• If you need Multipath support for future use, configure /etc/multipath.conf file on your
storage device (from the other storage vendor) as your target LUN.
5a. Make sure public key is there in the ~/.ssh folder:
