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
© 2008 NetApp. All rights reserved.
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
© 2008 NetApp. All rights reserved.
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)
© 2008 NetApp. All rights reserved.
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
© 2008 NetApp. All rights reserved.
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
© 2008 NetApp. All rights reserved.
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
© 2008 NetApp. All rights reserved.
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
