Can You Create A Replication Set; Diagnostics For Replication Setup: Creating A Replication Set - HP MSA 2040 User Manual

Can you create a replication set?

Answer Possible reasons
Yes System functioning properly.
No Selected link type or port-to-link
connections are incorrect.
No On controller enclosures with iSCSI
host interface ports, replication set
creation fails due to use of CHAP.
No Unable to select the replication
mode (Local or Remote)?
No Unable to select the secondary
volume (the destination volume on
the vdisk to which you will replicate
data from the primary volume)?
No Communication link is down.

Diagnostics for replication setup: Creating a replication set

Actions
No action required.
• Remote Replication mode: In the Configuration View panel in
the SMU, right-click the remote system, and select Tools > Check
Remote System Link. Click Check Links to verify correct link type
and remote host port connections.
• Local Replication mode: In the Configuration View panel in the
SMU, right-click the local system, and select Tools > Check Local
System Link. Click Check Links to verify correct link type and
local host port connections.
If using CHAP (Challenge-Handshake Authentication Protocol),
configure it as described in the SMU topics "Using the Replication
Setup Wizard" or "Replicating a volume."
• In the SMU, review event logs for indicators of a specific fault in
a host or replication data path component. Follow any
Recommended Actions.
• Local Replication mode replicates to a secondary volume
residing in the local storage system.
• Verify valid links.
On dual-controller systems, verify that A ports can access B
ports on the partner controller, and vice versa.
• Verify existence of either a replication-prepared volume of
the same size as the master volume, or a vdisk with sufficient
unused capacity.
• Remote Replication mode replicates to a secondary volume
residing in an independent storage system:
• Verify selection of valid remote vdisk.
• Verify selection of valid remote volume on the vdisk.
• Verify valid IP address of remote system network port.
• Verify user name with Manage role on remote system.
• Verify user password on remote system.
NOTE: If the remote system has not been added, it cannot
be selected.
• In the SMU, review event logs for indicators of a specific fault in
a replication data path component. Follow any Recommended
Actions.
• Verify valid specification of the secondary volume according to
either of the following criteria:
• Creation of new volume on the vdisk
• Selection of replication-prepared volume
See actions described in "Can you view information about remote
links?" (page 64).
