Overview
Capabilities
HP StorageWorks Replication Solutions Manager is a centralized tool that simplifies and automates local
and remote replication features of HP arrays. The replication manager allows you to perform tasks by
using its graphical user interface (GUI), jobs, and a command line user interface (CLUI).

CAUTION:
HP strongly recommends that you do not run simulation mode on a production machine (that is, on the same
machine as Command View EVA). If you disconnect the replication manager from Command View EVA, you
lose control of the storage resources that were being managed by the replication manager. If you purge the
replication manager database and have not backed it up, you will lose all jobs.
Overview
Simulation mode allows you to use all of the functions of the replication manager without having to use
any of your production data or resources. These functions include creating snapshots and snapclones,
creating DR groups and adding virtual disks to them, and performing failovers.
Features and benefits:
• No SAN infrastructure, storage arrays, hosts, or management servers are required.
• Requires only replication manager server software running on a business class Windows desktop
or laptop computer.
• True simulation – not a set of predefined scenarios. Simulates GUI actions, jobs, and CLUI
commands.
• Allows you to create your own:
• Simulated storage arrays. Select features such as array capacity, software controller versions
and number of virtual disks.
• Simulated hosts. Include hosts and select the storage arrays they are connect to.
• Simulated Oracle databases. Simulate Oracle databases, tablespaces, datafiles, archived
redo logs, control files, and repositories.

RSM database
About the RSM database
The RSM database contains information on available resources, jobs, job instances, replication manager
events, and DC-Management settings. The database is updated through several methods, including
real-time updates, automatic refreshes, and manual global refreshes. See refreshing resources (automatic)
and refreshing resources (global).
The active RSM database cannot be accessed by administrators or users. Administrators, however, can
export and import copies of the database. See exporting an RSM database, impor ting an RSM database
and importing a remote RSM database.
About exports
Theexportfeaturecreatesacopy(XMLfile) of the active RSM database.
• Exported copies can only be created in an existing folder on the storage management server.
• You can assign a file name or let the replication manager automatically assign a name.
• Automatically assigned file names have the format: CADATA_timestamp.export.xml
where timestamp is the year, month, day, hour, minute, and second the file was created. For
example, the file CADATA_20050211135232.export.xml was created on February 11,
2005, at 13:52:32 hours.
• Stored security credentials for resources and scheduled job events are not included in the
exported copies.
• All scheduled job events are exported with a status of a run status of disabled. See
Enabling and disabling scheduled job events.
• See also exporting an RSM database.
About imports
The import feature merges the content of a previously exported RSM database or a remote RSM database
with the content of the currently active database.
• Importingprocessingisasfollows:
40
Replication Solutions Manager
When a storage or host resource exists in both the imported and active RSM database, the active
database record is overwritten with the imported record.
When a storage or host resource exists only in the impor ted RSM database, a record is added to the
active da tabase.
When a job or managed set exists in both the imported and active RSM database, the active database
record is not overwritten. Instead, a new record is added and the job or managed set name is modified
with the characters _# to make it unique.
• After an import has been run, additional procedures are required to make the imported resources
available. See completing imports.
• See also importing an RSM database and importing a remote RSM database.
Exporting an RSM database
This feature allows administrators to create a copy of the active RSM database. The copy is created on
the same management server as the active database. See RSM database.
Considerations

Troubleshooting
Troubleshooting - G eneral
All storage resources in unknown state
Problem
The status of all storage systems, DR groups, and virtual disks have changed to an unknown state.
Explanation / resolution
The RSM administrator should check if the replication ma nager database was recently imported
from another management server. See resources database. If so, the problem is probably that the
management server passwords are different. Passwords for the active and standby management servers
must match for the database import to succeed.
To change the password for a management server:
1. From the toolbar, select Tools > Configure > Storage Access > Management Server.
2. Select the management server for which you want to change the password. The server shows a
state of authorization_failure or bad_connection.
3. Click Properties.
4. In the Storage Agent Login area, Agent Password box, enter the correct password.
5. Click OK.
Browser window is blank
Problem
The replication manager GUI is blank (gray) in the browser window.
Explanation / resolution
This can b e caused by browsing away from, and back to, the replication manager.

Database file name extension is missing
Problem
When viewing an exported copy of the replication manager database on the management server (that is

Explanation / resolution
When a copy is created, the file name is automatically assigned in the following format:

InvalidDRgrouppair-sourceandsource
Problem
Both groups in a suspended DR group pair are identified as the source group.
Explanation / resolution
If a D R group pair is suspended while the intersite links are unavailable, when the intersite links become
available again both DR groups are identified as the source. The source-source identifi cation continues
until remote replication is resumed.
Thiscanhappenwhen:
• The DR g roup pair is suspended while the intersite links were unavailable. See suspension state.
• The DR g roup pair is failed over with the suspend-on-failover action while the intersite links
were unavailable. See suspend on failover.
• Auto suspend mode is enabled while the intersite links are unavailable. See auto suspend.
To resolve this issue
1. Use HP Command View EVA to resume the suspended DR group pair.
2. After resuming the DR group pair, perform a manual refresh of the DR groups. See
low-level refreshing DR groups. The source and destination DR groups are correctly identified.
HP StorageWorks Replication Solutions M anager
45
NOTE:
While the incorrect source-source identification exists:
•
The GUI Actions menu correctly shows only actions that are appropriate for the true role of the DR group
(source actions for the true source and destination actions for the true destination).
•
In the CLUI, issuing a Show DR_group command on the "new source group" shows it correctly it as a
destination and only destination operations can be executed.
Invalid DR group settings - failsafe with synchronous
Problem
When attempting to use C LUI commands to disable the failsafe mode, the replication manager l ogs
the message:
Failed to set failsafe for DR Group, group is currently :failsafe is
already enabled.
Explanation / resolution
You can use GUI actions or CLUI commands to create a DR group pair with the following invalid
configuration: failsafe mode enabled with synchronous remote replication I/O mode. Attempting to
disable the failsafe mode in this invalid configurationresultsinanerror.
To resolve this issue, use the GUI or CLUI commands to set a valid confi guration. To retain an
asynchronous I/O mode and disable the failsafe mode:
1. Change the remote replication I/O mode to synchronous.
2. Change the failsafe m ode to disabled.
3. Change the remote replication I/O mode back to asynchronous.
Job instance fails with get error lock message
Problem
A job instance fails with a message like: get error lock failed.
Explanation / resolution
Too many job instances that interact with a specific enabled host may be running simultaneously. See
simultaneous job instances.
To resolve the problem, reduce the number of running job instances that involve the enabled host.
Job interacts with wrong array
Problem
When a job is run, storage commands are attempted on the wrong array. Typically, the job does
not validate properly or fails.
Explanation / resolution
If two storage arrays in a replication manager configuration have the same name, a job can attempt to
interact with the wrong array. Ensure that all arrays have unique names.
Job with host volume remount fails after an unclean unmount
Problem
A job with host volume remount fails and the replication manager logs the error message:
46
Replication Solutions Manager
The filename, directory name, or volume label syntax is incorrect for the
operating system associated with this mount point.
Explanation / resolution
If a host volume is uncleanly unmounted, such as during an unplanned failover, the host OS or file system
may retain information about the host volume. When the replication manager attempts to remount that
same volume, the host treats the request as a duplication and the remount fails. To resolve this issue:
1. Ensure that the host volume is cleanly unmounted.
2. If necessary, clean up resources that were involved in the failed job.
3. After the host volume is cleanly unmounted, you can aga in use the replication manager to
mount it.
Logical volumes and volume groups in job commands
Some command arguments require the selection or entry of a logical volume (a com ponent of a volume
group). Because the replication manager considers logical volumes and volume groups to be host
volumes, you must select the resource from a host volumes list. There is not a separate list of logical
volumes or v
olume groups.
See also, host volumes and logical volumes and volume groups.
Low-level refresh returns an error
Problem
When you perform a low-level refresh on a virtual disk or DR group, the replication manager may
log the message:
Unable to complete the requested action because of an unexpected error.
Explanation / resolution
This ca n o ccur when the replication manager is unable to discover a virtual disk or DR group. Use HP
Command View EVA to verify that the virtual disk or DR group exists, and then retry the low-level refresh.

Maximum DR Group log size error
Problem
If you enter an invalid size, the replication manager logs an error and does not set the maximum log
size for the DR group.
Explanation / resolution
Invalid sizes are ignored.

Scheduled job event run times are wrong (AM/PM)
Problem
Symptoms that can indicate this problem:
• When using the Schedule a Job wizard, a time of day entered as PM appears as AM on the
final page.
• A scheduled job runs at an unexpected time.
HP StorageWorks Replication Solutions M anager
49
Explanation / resolution
This can occur due to a non-English setting on a Windows-based storage management server. A
non-English setting changes the time entered in the Schedule a Job wizard to an AM time. For example, a
time entered in the wizard as 2:00 PM is saved as 2:00 AM.
To correct this problem, perform the following procedure. You must be a member of the server’s
Administrators group.
CAUTION:
Performing this procedure requires a reboot.
1. Coordinate reboot activities to avoid disruption of services to others. Ensure that no replication
manager jobs are running or are scheduled to run during the reboot.
2. On the Window-based storage management server, select Start > Control Panel > Regional and
Language Options > Advanced tab.
3. On the Advanced tab, under Standards and formats, select Englis h (United States).
4. Click OK and follow the Windows on-screen instructions.
5. When prompted, reboot the computer. Click Yes to complete the change to Windows.
6. In the replication manager, edit any scheduled job events that had incorrect run times. See
Editing scheduled job events.

Second snapclone of the same storage volume or host volume fails
Problem
Thesecondsnapcloneofthesamestoragevolumeorhostvolumefailsandthereplicationmanager
logs a message like:
Copy type CLONE not available or no resource bundle
Explanation / resolution
You can make multiple snapclones of a source volume. However, only one snapclone can b e in the
normalization (unsharing) phase at one time. If the second snapclone action is started too soon, the
action can fail.
This issue can occur when:
• You run and then quickly rerun the same job.
• The replication ma nag er database was not refreshed after the first snapclone was completed.
When the second snapclone is requested, the replication manager encounters the out-of-date
normalization status in the database and fails the requested snapclone action.
To resolve this issue:
• Allow sufficient time after between snapclones to allow the unsharing process to complete.
• Allow sufficient time between snapclones to allow the replication manager database to be
refreshed.

group appears to still be active and the command fails.
To resolve this issue, you must reboot the enabled host:
IMPORTANT:
Before proceeding, coordinate the reboot activities to avoid disruption of host services to others.
1. Ensure that no replication manager jobs involving the host are running or scheduled to run
during the reboot.
2. On the enabled host, close applications, as appropriate.
3. Reboot the host. This clears the device minor numb ers for the host memory.
4. Restart applications on the host, as appropriate.

Job with MountEntireVolumeGroup command fails - HP-UX
Problem
A job that replicates and mounts an HP-UX volume group fails at a MountEntireVolumeGroup command
when attempting to mount the volume group on an enabled host. The replication manager logs a
message such as:
Host Volume has unknown or incompatible ...
Explanation / resolution
This can occur when a job is rerun.
IfthereplicationmanagerdiscoversanHP-UXvolumegroupatthesametimethatajobcommandis
attempting to remove the volume group, an error allows the underlying storage to be unpresented from
the host, even though the volume group is still active.
When the job is run again, the volume group cannot be replicated and the job fails at the mount step
because there is no underlying storage available.
To resolve this issue:
1. In the replication manager or HP Command View EVA, correct the presentation of the underlying
storage for the volume group.
2. If necessary, clean up resources that were involved in the failed job.
3. Rerun the job.
Host volume with PVLinks multipathing
Problem
If the source host volume uses HP-UX PVLinks for multiple paths, a replica will have only one path defined.
Explanation / resolution
When replicating a host volume with PVLinks multipathing, replication manager jobs define only one
path in the replica. If necessary, you can use PVLinks to add paths to the replica after the job is finished.
See CreateHostVolume and CreateHostVolumeGroup job commands.
Troubleshooting - Linux

Replication Solutions Manager
A job that creates a Linux host volume runs slowly or appears to hang.
Explanation / resolution
First, check the job to see if it contains one of the following commands:
CreateHostVolume CreateHostVolumeDiscrete CreateHostVolumeGroup
If so, one of the following conditions may apply.
Host QLogic HBA driver LUN setting is exceeded
The d efault support for QLogic HBA drivers is 32 LUNs (virtual disks). If there are more than 32 LUNs
(which is typical with EVA storage systems) the create host volume style commands can execute for an
extended period of time because the LUN is not found on the host.
To resolve this problem:
1. On the enabled host, open the probe-luns fi le in a text editor. It is located at:
/opt/hp/hp_fibreutils/probe-luns
2. In the file, modify the LUNEND variable to allow for the number of LUNs in your situation.
Save the file.
3. If necessary, clean up resources that were involved in the failed job.
4. Rerun the job.
Host QLogic HBA driver is frozen
If the QLogic HBA driver is frozen, none of the LUNs may be visible to the host.
To resolve this issue:
1. On the enabled host, reload the QLogic HBA driver or reboot the host.
2. If necessary, cleanup resources that were involved in the failed job.
3. Rerun the job.

A job is run that mounts, unmounts, and remounts a host volume (for example, drive F) on a Windows
enabled host.
After the job completes successfully, Windows Explorer on the host does not show the disk (drive letter
F). The disk does appear in the host Disk Management window, but Open and Explore operations
on the disk fail.
Explanation / resolution
The dynamic remounting (mount without a reboot) step in the job causes the host OS to loose track of
some drive information.
To resolve this issue:
1. Ensure that no replication manager jobs involving the host are running or scheduled to run
during the reboot.
2. On the enabled host, close applications, as appropriate.
3. Reboot the host. This clears the drive information issue.
4. Restart applications on the host, as appropriate.

any of your production data or resources. These functions include creating snapshots and snapclones,
creating DR groups and adding virtual disks to them, and performing failovers.
Features and benefits:
• No SAN infrastructure, storage arrays, hosts, or management servers are required.
• Requires only replication manager server software running on a business class Windows desktop
or laptop computer.
• True simulation – not a set of predefined scenarios. Simulates GUI actions, jobs, and CLUI
commands.
• Allows you to create your own:
• Simulated storage arrays. Select features such as array capacity, software controller versions
and number of virtual disks.
• Simulated hosts. Include hosts and select the storage arrays they are connect to.
• Simulated Oracle databases. Simulate Oracle databases, tablespaces, datafiles, archived
redo logs, control files, and repositories.

Oracle-integration licenses overview
To use the replication manager’s Oracle-integration features with a given array, the replication manager
verifies that appropriate HP Oracle-integration licenses exist for that array.
• For information on acquiring and installing Oracle-integration licenses, see the HP StorageWorks
Replication Solutions Manager a dministrator guide.
• Oracle-integration licenses are verified during automatic and global refreshes. See
refreshing resources (automatic) and refreshing resources (global)
• Oracle-integration license status is displayed in the GUI. See license status.

• Expiration date (if any)
• Capacity range (amount of storage)
• Multi-array resources. If an Oracle resource such as a database or tablespace is comprised of
virtual d isks on two or more arrays, each array must have an HP Oracle-integration license.
• GUI actions. Some GUI actions may be disabled if an applicable HP license is not verified.
Disabled actions appear in gray and cannot be selected. A tooltip indicates why the action
cannot be performed. See tooltips.
For example, if you select an Oracle database and the Replicate Database (Snapclone) action is disabled,
itcanbebecausethestoragesystemthatcontainsthedatabasedoesnothaveanappropriatelicense.
• Job commands. Some job commands m ay not be executed if an applicable HP license is not
verified when a job is run. An event in the job log indicates the command d id not execute due
to a licensing issue.
For example, if a CreateHostVolumesUsingRepository command in a job did not execute when the
job was run, it may be because a storage system on which the database is located did not have an
HP Oracle-integration license.
IMPORTANT:
HP recommends that you include validation commands in jobs and perform validation tests to prevent or
minimize the effect of license-related issues at run time.
Replication l icenses overview
To use loc al and remote replication features on a given array, the replication manager verifies that
appropriate HP replication licenses exist for that array.
• For information on acquiring and installing local replication licenses, see the HP StorageWorks
Business Copy EVA administrator guide.
• For information on acquiring and installing remote replication licenses, see the HP StorageWorks
Continuous Access EVA administrator guide.
• Replication licenses are verified during automatic and global refreshes. See
refreshing resources (automatic) and refreshing resources (global).
• Replication license status is displayed in the GUI. See license status.
Replication license policies
HP license policies determine how the replication manager interacts with resources that require HP
replication licenses.
The following summarizes the policies.
• Verification.Licenseverification includes factors such as:
•Typeoflicense
• Expiration date (if any)
• Capacity range (amount of storage)
• Multi-array volumes. If a volume is comprised of virtual disks o n two or more arrays, each array
must have an HP replication license in order in order to be considered fully licensed.
• GUI actions. Some GUI actions may be disabled if an applicable HP license is not verified.
Disabled actions appear in gray and cannot be selected. A tooltip indicates why the action
cannot be performed. See tooltips.
For example, if you select a virtual disk and the New Snapclone action is disabled, it can be because the
storage system that contains the disk does not have a local replication license.
• Job commands. Some job commands m ay not be executed if an applicable HP license is not
verified when a job is run. An event in the job log indicates the command d id not execute due
to a licensing issue.
66
Replication resources
For example, if a SnapcloneStorageVo lume command in a job did not execute when the job was run, it
may be bec ause the storage system that contains the disk did not have a local replication license.
IMPORTANT:
HP recommends that you include validation commands in jobs and perform validation tests to prevent or
minimize the effect of license-related issues at run time.
• CLUI commands. CLUI commands that run jobs or create implicit jobs behave like job commands.
An event in the job log indicates that the command did not execute due to a licensing issue.
Dynamic capacity management license policy
The DC-Management feature requires an array-based DC-Management license in RSM.
DC-Management license
RSM 3.1 ships with an instant-on license for the DC-Management feature. The instant-on license is valid
for 60 days from the time of install, after which you may request an extension to the license. This license
enables the DC-Management feature for all arrays during the validity period.
When the instant-on license expires, the DC-Management feature is disabled unless a permanent license
is installed. Permanent licenses are installed on a per-array basis.
The DC-Management license can be viewed, retrieved, and added by selecting Tools > Configure >
Licensing.
Security Credentials
Security credentials for the server
To establish and manage replication manager server security credentials, administrators must use the
OS on the m anag em ent server See security groups configuration and the HP StorageWorks Replication
Solutions Manager installation guide and HP StorageWorks Replication Solutions Manager administrator
guide.
Server security credentials (user name and password) must be provided for the following cases:
• GUI logon. To access the GUI, you must enter replication manager security credentials in the
logon window.
• Creating a scheduled job event. To schedule a job event, you must enter replication manager
security credentials in the Schedule Job window.
• CLUI logon. To access the CLUI via any method other than the GUI, you must enter include
replication manager security credentials in the CLUI logon commands.
Passw or d change considerations
Administrators should carefully plan and coordinate sever security credential changes with replication
manager operations. For example, if the security policy in your environment is to reset passwords every
six m onths, consider that such changes can result in the following:
• Logging on to the GUI is prevented
• Scheduled job events are p revented from running.
• Logging on to the CLUI is prevented.
Security credentials for enabled hosts
To establish and manage replication man ager host agent security credentials, administrators must use
the OS on each enabled host. See security groups configuration and the HP StorageWorks Replication
HP StorageWorks Replication Solutions M anager
67
Solutions Manager installation guide and HP StorageWorks Replication Solutions Manager ad ministrator
guide.
For an enabled host to interact with the server, a valid host agent security credential must be
present in the replication manager database. See setting security credentials for enabled hosts and
adding a new enabled host.
IMPORTANT:
If a valid security credential is not entered or if the credential expires or is changed, the replication manager
(GUI, jobs, and CLUI) will not be able to interact with the enabled host.
Hostagentsecuritycredentials(usernameandpassword)mustbeprovidedforthefollowingcases:
• New enabled host. To add a new enabled host to the replication manager database, an
administrator must enter a valid security credential.
• Changed credentials. To update the security credential that is saved in the database, an
administrator must enter a new security credential.
• Imported RSM database. After importing an RSM database that includes enabled hosts, an
administrator must re-enter the security credentials.
Password change considerations
Administrators should carefully plan and coordinate host agent security credential changes with
replication manager operations. For example, if the security policy in your environment is to reset
passwords every six months, consider that such changes can result in enabled hosts n ot interacting with
the replication m anager server. This can lead to the following:
• Jobs that interact with impacted enabled host do not validate or fail while running.
• CLUI commands that interact with impacted enabled host fail.
• Enabled host and host volume information is not updated in the server.
• Oracle d atabase information is not updated in the replication manager server.
Security credentials for Oracle databases
For the replication manager to interact with an Oracle application, an account for the replication manager
must be established by an Oracle database administrator. See the HP StorageWorks Replication Solutions
Manager installation guide and HP StorageWorks Replication Solutions Manager administrator guide.
For the replication manager to interact with an Oracle database, a valid security
credential for the database must be present in the replication manager database. See
setting security credentials for Oracle databases.
IMPORTANT:
If a valid security credential is not entered or if the credential expires or is changed, the replication manager
(GUI and jobs) will not be able to interact with the Oracle database.
Oracle database security credentials (user name and password) must be provided for the following cases:
• New Oracle database. To add a new Oracle database to the replication manager database, an
strator must enter a valid security credential.

• Changed credentials. To update the security credential that is saved in the database, an
administrator must enter a new security credential in the Set Credentials window.
• Impor

Passw or d change considerations
Administrators should carefully plan and coordinate Oracle database security credential changes with
replication manager operations. For example, if the security policy in your environment is to reset

Filters
• You can have multiple m a nag ed sets that are used as filters. However, only one managed set can
be applied as a filter at one time.
• If you create an empty (but applicable) managed set and apply it to a view, no objects are
displayed.
• If you create a managed set only for the purpose of filtering a view, H P recommends that you
assign a filter-related name. For example, you might assign a na me like: disk filter - sales

This can help to quickly identify the type of filter. It can also help reduce the chance of subsequently
applying an action to the managed set (in the managed set content pane) that might be undesirable,
for example attempting to create snapshots of all the virtual disks in the man age d set.

DR group concepts
DR group pairs (source and destination)
DR groups operate in a paired relationship, with one DR group being a source and the other a
destination.Thetermssource and destination are sometimes referred to as a DR mode or DR role. The
terms source and destination are also applied to virtual disks, with a destination virtual disk also being
known as a remote copy. Various actions, such as a planned or unplanned failover, allow you to
reverse the relationship so that the source DR group becomes the destination and destination becomes
thesource. SeeDRgroupsfailover.
IMPORTANT:
The role of a DR group in remote replication is of critical importance and can be reversed at any time.
For example, a DR group can be a source at 8:00 and then, after a user-initiated failover, be a destination at
8:05. When reviewing a DR group’s role, ensure that you are looking at current properties.
In a typical environment, hosts perform I/O with the virtual disks in the source D R group at one site and
the data is remotely replicated to the destination D R group at another site. The virtual disks in a source
DR group remotely replicate to the same destination, fail over together, share a DR group log, and
preserve write-order within the group.

HP StorageWorks Replication Solutions M anager
95
Site 1 < remote link > Site 2
A DR group log is a designated virtual disk in a source D R group that is used under certain circumstances
to temporarily store host writes to source virtual disks. Logging can be started automatically when remote
replication to the destination DR group cannot be performed, for example when a remote link is down.
Logging can also be started on demand by performing a suspend action from the GUI, jobs, or a CLUI
command. When remote replication is re-established, the contents of the source DR group log are written
to the destination virtual disks. See DR groups logs.
Home group and home configuration
When designated as a home group, the group is considered be the preferred source in the remote
replication relationship. By default, the property for the source and destination DR group is set true and
false,respectively. Thisiscalledthehome configuration.SeeDRgroupshome.
DR group names
When a DR group pair is created, the same DR group name is assigned to the source and destination
DR group.
IMPORTANT:
After creation, HP recommends that you edit partner DR groups and change the names.
96 DR Groups
After creation, you can change the names to something logical for your environment. For example,
rename them based on their physical locations, Boston and London, or their home roles SiteA_Srce and
SiteB_Dest. Certain characters are illegal in the names. See illegal characters.
Auto suspend
Auto suspend s
pecifies whether remote replication in a D R group pair is automatically suspended after a
remote link goes down. Values are:
• Enabled. Remote replication in the DR group pair is automatically suspended after a remote
link goes down
.
• Disabled. Remote replication in the DR group pair is not automatically suspended after a remote
link goes down.
Usage guidel
ines:
• Remote replication is not automatically restarted after the link becomes operational again.
IMPORTANT:
A resume command must be issued to resume remote replication.
• Improper use of auto suspend can create and invalid source-source configuration. See
invalid DR group pair - source and source.
IMPORTANT:
Do not set auto suspend when the links are down
, especially during an unplanned failover.
• If not specified when creating a DR group pair, the value is set to disabled.
• You cannot change this property when failsafe mode is enabled. See DR groups failsafe mode.
See also DR groups suspension state.
Controller software versions
Implementation of this feature is controller software depend ent. See
controlle
r software features - remote replication.
Cascaded replication
Cascaded replication refers to a replication event, and a configuration, that involves three sites (storage
systems). See the diagram blow.
The source volume (a) at site 1 is in a remote replication relationship with its copy (b) at site 2. Whenever
a point-in-time snapclone copy is needed (c) , it is created at site 2. The snapclone copy is then remotely
replicated (cascaded) to another remote copy (d) at site 3.
Site 1 Site 2 Site 3

The result is that a point-in-time replica of the source exists at two different sites.

Values are:
• Normal.Remote
involving the virtual disk.
• Full Copy. The DR Group log threshold has been reached and the virtual disk is involved in
a full copy. See DR groups full copy mode.
replication involving the virtual disk is normal. There is no logging or merging
Destination access mode
Destination access mode specifies the type of host I/O that is allowed when a virtual disk is in a
destination (remote copy) role. Values are:
• None. Thevirtualdiskcannotbepresentedtoanyhosts.
• No Read. The virtual disk can be presented to hosts, but no reads (or writes) are allowed.
• Read Only. The virtual d isk can be presented to hosts for read only.
The no read mode allows SCSI inquiry but prohibits host reads. This mode is typically used to support
host clusters.
Controller software versions
Implementation of this feature is controller software dependent. See
controller
software features - remote replication.
DR group states and icons
Icons in the DR group content pane indicate the key states of each DR group. You can mouse over an
icon to display a detailed state message.
1. Operational state
2. Failsafe state
Failover
To fail over means to reverse the direction of remote replication in a DR group pair. A failover event
is an event in which the remote replication direction was reversed.
When a failover event occurs, the roles of source and destination in a DR group pair are reversed.
For example, in a planned failover, if DRgroupA was originally the source and DRgroupB was the
destination, those roles are reversed when DRgroupB is failed over.
In the case of an unplanned failover (disaster), there may not be a literal reversal of remote replication
because SiteA may not be operational. Instead, when DRgroupB is failed over, S iteB may become an
independent site, or a source that remotely replicates to third site.
Performing a planned or unplanned failover involves technical preparation and significant operational
planning. Host I/O is impacted by a failover. The following guidelines capture just a few of the
technical considerations.
3. Suspension state
4. Log state
98 DR Groups
• To fail over a DR group pair, you must specify the destination DR group. See DR group pair.
• You cannot fail over a DR group pair if remote replication is suspended or if a remote copy (virtual
disk)isinanunknownstate. SeeDRgroupssuspension state and virtual disks resource states.
• If only one component in a DR group pair fails, repairing that single component may be
preferable to performing a failover.
IMPORTANT:
Failing over a DR group pair impacts host I/O. Ensure that you understand the potential imp acts of
performing a failover.
See also DR groups suspend on failover and remote replication guidelines.
Failsafe mode and states
Failsafe mode specifies how host-writes, logging, and remote replication occur when a component in
the DR pair fails. Values are:
• Enabled
• Disabled. Host writes and remote replication continue normally while all components in the DR
group pair are functioning normally.
Failsafe mode enabled
When failsafe mode is enabled, there are two operational states.
• Host writes and remote replication c ontinue normally while all components in the DR group pair
function normally. This is the failsafe unlocked state.
• Host writes and remote replication stop (are locked) when any virtual disk in the DR group pair
fails or becomes unavailable. This is the failsafe locked state.
Failsafe mode disabled
When failsafe mode is disabled:
• All host writes and remote replication continue normally as long as all components in the remote
relationship are functioning normally.
• If any remote copy (virtual disk) in the DR group pair fails or becomes unavailable, all host
writes to the source DR group continue, but all remote replication to the destination D R group
automatically stops. Host writes are stored in the source DR group log until remote replication is
re-established.
• If a source virtual disk fails, host writes to the failed disk automatically stop. Remote replication
to the remote copy automatically stop, too. Host writes and remote replication to other virtual
disks in the source and destination DR groups continue normally.

Full copy mode is when data in a DR group pair is copied directly from the source group virtual disk to the
destination group, without using any data in the log disk. Typically, this is an automatic event that happens
when remote replication is resumed and the DR group log disk is full. See default maximum log size.
Force full copy
Inaforcedfullcopy:
• All virtual disks in the source DR group are copied; you cannot copy individual disks.
• All host write-transactions in the DR group log are deleted.

Even when supported by the controller soft ware, the force full copy feature is not available if conditions in
the DR group pair are not appropriate.
Controller software versions
Implementation of this feature is controller software dependent. See

Home
When designated as home, the DR group is the preferred source in the DR group pa ir. Values are:
• True/Yes. The DR group is the preferred source.
• False/No. The DR group is the preferred destination.
Home group is a property that is maintained only by the replication manager.
Home configuration
When the replication manager creates a DR group pair, the h om e property for the source and destination
groups is set to true and false, respectively. This is called the home configuration.Whenfailedover
from the home configuration, the home property remains u nchanged.
Reverting to home
Reverting to home is an event that causes a failed over DR group pair to return to their original roles in
the home configuration.

Use of home
The home concept is useful because the preferred source is flagged by the home property, even if it is
currently operating as the destination. This helps you to revert to home configuration easily.
Consider using home group to designate a business center for your replication activities. For example, if
your headquarters is in Chicago, you can set your Chicago DR group as home. If your headquarters
moves or becomes inoperable, you can then change home to some other location.
I/O throttling
I/O throttling refers to suspending some DR groups during a log merge or full copy event. By suspending
non-critical DR groups, the critical DR groups complete the merge or full copy sooner.
Throttling of I/O after logging
When logging, and not in the failsafe mode, remote replication automatically resumes when the links
are restored. If there are several DR groups with large logs, they can compete for remote replication
bandwidth, thus slowing the overall merge or full copy between the two sites.
By suspending the merge or full copy of the non-critical DR groups, the critical data is available sooner
at the destination. After the critical DR groups finish merging or copying, the remote replication of the
non-critical DR groups can be resumed.
