Cisco UCS Invicta Scaling System Administration and Configuration Guide, Version 5.0.1.1a
Chapter 5 Asynchronous Replication
Note This example uses CentOS 6.2.
You need the following:
• 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:
• $ cd ~
• $ chmod 755 .ssh
• $ chmod 600 ~/.ssh/authorized_keys
• (Do a cat authorized_keys and make sure the public key is copied there)
• $ exec /usr/bin/ssh-agent $SHELL
• $ ssh-add
5b. As the Linux root user, type the following command to relabel all the files under the correct
security context for SELinux:
restorecon -Rv /root/.ssh
(These should allow the Cisco array to communicate with the Linux host via password-less ssh)
Step 6 Close the session on the remote replication site.
Return to the Async Replication window to create a pairing (see Create a Pairing, page 5-7).
Cisco to Windows
Note The Windows Server firewall must be turned off before Async Replication can be set up.
Cisco-to-Windows Async Replication requires that Cygwin along with two services, sshd and
cyg_server, are installed on the target Windows machine. An automated method for downloading this
software is provided on the Async Replication window.
To install the Windows software package and to configure for the Async Replication to run, do the
following:
Step 1 Login to the Windows 2008 R2 Server machine as Administrator and open a browser to go to Cisco page.
Step 2 Choose Async Replication > Pairings.
The Async Replication window appears.
