Security credentials for enabled hosts
To establish and manage replication manager host agent security credentials, administrators must
use the OS on each enabled host. See security
or the HP P6000 Replication
Solutions Manager Installation Guide and HP P6000 Replication Solutions Manager Administrator
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
.
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.
Host agent security credentials (user name and password) must be provided in the following cases:
•
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 replication manager database. After importing a replication manager 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 not interacting
with the replication manager 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.
Host names and ports
HP recommends that you use the same host name in HP P6000 Command View and the replication
manager to identify each host. This provides consistency in both interfaces when presenting a
virtual disk to a host.
An enabled host's storage system communication ports that are shared with HP P6000 Command
View are listed in the Enabled Hosts properties window, P6000 EVA Hosts tab. See
VM servers
VM servers are included with the enabled host resources in HP P6000 Replication Solutions
Manager. However, VM servers differ from enabled hosts in some important respects:
•
An HP P6000 Replication Solutions Manager host agent is not installed on the VM server
itself. HP P6000 Replication Solutions Manager recognizes a VM server but does not interact
with it directly to perform replication tasks.
•
The operating systems running on the VM server are added to HP P6000 Replication Solutions
Manager as guest OS-enabled hosts. This distinguishes them from traditional enabled hosts.
•
The appropriate HP P6000 Replication Solutions Manager host agents are installed on each
guest OS on the VM server.
