When the Physical Space option is selected from the right-click menu, the following information is
provided:
Caution
•

•
Available Free Space
•
Data Reduction Savings
Avoid filling up a 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.
Physical Space Alerts
The status of physical space is monitored on an hourly basis. Alerts are triggered at the capacities and
frequencies listed in Table 3-2. These messages can be viewed from the Array Configuration menu under

Asynchronous Replication
•
Communicating with a Partner Host, page 5-2
•
Create a Pairing, page 5-7
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.
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.
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 you use the Asynchronous (Async) Replication feature, make sure that you do not use the
LUN or Snapshot "Snapdiff1_xyz" as the name (where 'xyz' is either the Source or Target, LUN, or
Snapshot name) because the user data might get deleted 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 available free space on the system falls below a threshold level of 10%, on both the Async
Replication Source or Destination, the system automatically deletes the oldest Snapshot(s) on the
device to free up at least 15% of space. Neither manual nor scheduled Snapshots can be created until
this 15% threshold is met.
•
If either the Source or Destination LUN used for Async Replication has a Snapshot merge in
progress, neither manual nor scheduled Snapshots can be created until the merge is complete
causing Async Replication to fail.
Cisco UCS Invicta C3124SA Appliance Administration and Configuration Guide, Version 5.0.1.2a
5-1
Chapter 5
Asynchronous Replication
•
If an Async Replication or Restore is in progress for a given pairing, a LUN Merge operation will
not be permitted on a LUN that has either been configured as an Async Source or Destination until
the Replication or Restore operation is complete.
•
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:
– 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
•
Linux systems:
– Linux-LVM
– Linux-RAW
•

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:
Cisco UCS Invicta C3124SA Appliance Administration and Configuration Guide, Version 5.0.1.2a

$ 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

Create or Modify a Role
A Role is required for each User. Roles are a descriptive name given to a predefined set of permissions
that are assigned using the Roles Menu.

then log back in to be granted permission for the modified role.

Unassigned Permissions and the Assigned Permissions columns.
Note
Assign and/or unassign permissions to a role by selecting the check box adjacent to one or more entries
in the Assign/Unassign Permission columns.
Note
The permission to access and view a window, does not automatically give permission to actions available
on that page. Conversely, if permission is granted to perform an action, permission to the window where
that function is located must also be granted.
For example, LUNs window access must be permissioned along with a LUN action, for example, LUNs
Edit action.
