OL-31370-01

Chapter 3 Array Configuration

Caution Avoid filling up LUN to its storage capacity as this may cause the system to become unresponsive

Storage Trend (Data Reduction)

Storage Trends are used as a predictive tool to approximate how many days of storage use remain before
the storage array is fully saturated. Trends are based on data captured daily on the amount of storage
remaining.

Prediction strengths of high, medium and low probability are based on the quantity of data points and
regression analysis validation. If enough data has been collected, the Storage Trend graph draws a
statistically valid regression line, for example, 30 days of data points yields a prediction probability with
a high strength.

Trend calculations without sufficient or with inconsistent data points will be calculated, but can be
statistically weaker or inconclusive. If a calculation cannot be made based on the data points, a message
appears to indicate this status.

Asynchronous Replication

Communicating with a Partner Host, page 5-2

Create a Pairing, page 5-6

Asynchronous replication (hereafter referred to as Async Replication) is an optional and separately
licensed feature. It provides a permission-based mechanism to create a duplicate version of a LUN on a
device attached to a partner host.

Activation If you do not have the Asynchronous Replication feature activated but would like to use it, please contact

your Cisco Sales Representative or write to [e-mail].

Cisco uses block-level Async Replication and incorporates an Async snapshot feature to capture a
point-in-time state that allows applications to continue writing their data. These features help to prevent
damage from failures or disasters that may occur in one location and improves the ability to recover a
copy of the data in another location.

OL-25761-DRAFT

Note • LUNs must be 2TB or less to use Async Replication.

• During Async Replication pairing creation, if the source device is a LUN then the target device must

also be a LUN.

• Using target entities in Read-Write mode is not recommended as this poses a risk to the accuracy of

the data replication and may corrupt data recovery.

• Before using the Asynchronous Replication feature, make sure that no LUN names use

"Snapdiff1_xyz, to the LUN name (where ‘xyz’ is the original or target LUN name). Using this
naming conventions will delete user data during the replication process.

• During the replication process, the target LUN will be unmapped/unmounted and is therefore

inaccessible. This prevents possible corruption of source data. The replication process will
automatically re-map and remount at its completion. The source SSR will have access throughout
the replication process.

• When restoring to the original source LUN, the Restore process will unexport and unmount the

LUN and will not be accessible. The Restore process will automatically re-mount and re-export at
its completion.

• Once Async Replication pairing is setup, the following operations are prevented on the source LUN

used for the pairing:

Cisco UCS Invicta C3124SA Appliance Administration Guide

5-1

–

Increase in size

–

Delete operation

Note The first replication that is performed on a pairing is always a FULL replication. Subsequent replications

reflect the delta, except where an “Update Partner” operation is performed. In that case, the immediate
next replication would become a FULL replication.

Communicating with a Partner Host

To perform replication successfully, there must be a way for communicating between the local LUN and
the remote replication site to establish that the client (local Cisco Array) is allowed to invoke commands
on the server (remote replication site).

The Cisco Array uses the standard remote shell facility, ssh, leveraging on password-less access after
putting its public key to the proper location at the remote replication site.

For LUNs, Cisco supports open-target Async Replication. It can duplicate to the following platforms:

• Cisco Array

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:

• $ cd ~

OL-25761-DRAFT

• $ 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)

5c. Get your target LV device ready by using LVM2 tools.

With a multipath setup mapped, the target storage array from the other vendor is mapped as:

/dev/mapper/26439363962386365

5d. Setup the LV using the following commands

• pvcreate /dev/mapper/26439363962386365 vgcreate VG1 /dev/mapper/26439363962386365

• lvcreate -L 90G -n async_lun VG1

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 5-6).

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:

5b. As the Linux root user, type the following command to relabel all the files under the correct

security context for SELinux:

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.

Step 3 Click Windows Installer.

Note This step is to be used if Cygwin packages and services (sshd and cyg_server) are not already installed

on the Windows Partner Host. If the Cygwin packages and services are already installed, skip to Step 4.

The software package is downloaded and executed. If your browser downloads the software but does not
run automatically, click Run to install. The Cygwin packages will be downloaded from the Redhat
website and installed. The services required for Async Replication will be configured and started.

This setup will take several minutes.

Step 4 Click Public Key to obtain the public key necessary for using password-less ssh access.

The SSH Public Key dialog box appears.

Step 5 Copy the ssh key and click OK.
Step 6 Open a Terminal window and navigate to the /home/Administrator/.ssh directory.
