VMware Site Recovery Manager

What is SRM?– A DR workflow automation product

What does SRM do?– Simplifies DR, lowers cost and risk– Integrates VI3 with storage replication– Makes DR protection a property of the virtual machine– Allows a preprogrammed DR response

Vmware Requirements

Installed at BOTH Protected and Recovery Sites*:

– ESX Server 3.0.2, ESX 3.5 or ESXi 3.5

– VirtualCenter 2.5 and Virtual Infrastructure Client

– Site Recovery Manager 1.0

– NetApp Site Recovery Adapter 1.0

– Perl 5.8 (by default Perl is included in the SRM distribution)

* This information is current as of Sept 2008, please check latest documentation for up-to-date support

NetApp Requirements

Installed at BOTH Protected and Recovery Sites*:

– FAS 2000, FAS 3000, or FAS 6000 Series Storage platforms

– DATA ONTAP 7.2.2 or above

– NetApp APIs use simple HTTP by default. To use secure HTTPS, you must set up

SecureAdmin and ensure that ssl/ssh is running.

– Because SOAP/HTTP/SSL is used, you must configure the firewall (if any) between Data ONTAP and Site Recovery Manager to keep the corresponding port open

* This information is current as of Sept 2008, please check latest documentation for up-to-date support

NetApp License Requirements

NetApp licenses required on Protected and Recovery Storage:

– SnapMirror

– iSCSI and/or FCP

– FlexClone(required for creating flex clone volumes for Recovery Test)

Supported Replication Products

The following NetApp data replication products are supported with SRM on NetApp– Volume SnapMirror (async & sync)

– Qtree SnapMirror

The following is not supported– SnapVault

– MetroCluster

17

Supported Configurations

The following configurations are supported– NetApp FCP protocol– NetApp iSCSI protocol– NetApp FlexVol Volumes

The following configurations are not supported*– NFS protocol– Traditional Volumes

(FlexClone technology is not available with traditional volumes)

* This information is current as of Sept 2008, please check latest documentation for up-to-date support

Page 19: VMware Site Recovery Manager on NetApp Storage

Configuration Guidelines

FlexVol Volumes should be replicated to only one destination– LUNs having multiple replication destinations cannot be

failed over

NetApp SnapMirror replicates data at the volume or qtree level– Only VMs to be replicated should be contained in

replicated volumes

Guest attached storage – software iSCSI inside Guest, SRM does not recover this

storage

Applications running inside VMs are not application consistent

Failback – Reversing SnapMirror

If Primary storage recovered– SnapMirror “resync” in reverse direction

– Only delta of data transferred

– SnapMirror “update” during failback outage

If Primary storage lost– Snapmirror “initialize” in reverse direction

– All lost data transferred

– SnapMirror “update” during failback outage

Troubleshooting – Common Problems

Any issue with the Configure Array Manager– Verify the IP, username and password provided for the

NetApp array is correct

If Array Manager does not recognize replicated LUNs– Verify SnapMirror relationship exists between the

Protection and Recovery Filer and that the volume replicated contains LUN

During DR test no replicated datastore found– Verify Recovery storage has igroup type of vmware that

contains ESX initiators

– Verify replicated LUNs are not already mapped to igroup, SRM must map them

Page 37: VMware Site Recovery Manager on NetApp Storage

Common Problems, contd.

General NetApp issues– Verify SnapMirror, FCP, iSCSI and FlexClone products

are licensed

– Verify igroup types are created with ostype vmware

– Verify igroups contain ESX initiators

– Verify FCP, iSCSI, and SnapMirror service is running at Recovery site

Any issue with SRM Test Failover– Check if flexclone is licensed on the Recovery filer or not– Verify that no non-replicated datastores exist on the

recovery filer with the same names as the recovery datastore

– Remember, only FlexVol Volumes support this feature
