Configuration of a user account

HORCM_CONF configuration file
Setting Ext Stor configuration
Business Copy
In the case of an FC connection, host group security must
make one or more ON ports.
When using a disk array system of the XP P9500/XP7
series with VSS Provider, because it is assumed that the
authentication function is enabled, create a user account.
Assign the Storage Administrator authority (reading
authority and change authority) to the user account.
Assign the storage user account to meta_resource.
When connecting to the disk array system by FC, create
a host group.
Create a host group for every server to be connected,
and register the WWN of the connected server HBA.
When changing the HBA of the server, change the WWN
of the target host group. Specify Windows for the host
mode setting and do not switch from Windows.
Create a host group with the name "HP-VSS-HG". Do not
register WWN in "HP-VSS-HG".
When you perform a backup by using the Business Copy
function, map S-VOL onto "HP-VSS-HG".
Make a command device by using Storage Management
Software, and map it onto the host group of the target
server. The state of all mapped command devices must
be Normal.
Perform the following settings on a command device:
User certification : Valid
If the Ext Stor configuration is used by multiple physical
DKCs or HA configuration, place a command device in
meta_resource(RSG#0) of each physical DKC. Also, map
it onto the host group of the target server and command
devices of all physical DKC must be recognized.
Map the required command devices only. As all the
mapped command devices are processed, mapping
unnecessary command devices may cause performance
degradation.
Prepare the HORCM_CONF configuration file.
For details, see subsection 3.2.3.
In the case of the Ext Stor configuration or HA
configuration, do not describe HORCM_VCMD in the
HORCM CONF configuration file.
Do not use the HORCM CONF configuration file used by
VSS Provider except for the purpose of VSS Provider.
15. - When configuring Ext Stor, to create secondary VOL
(S-VOL/V-VOL) using VSS provider and GUI, assign the
physical LDEV ID to RSG which P-VOL belongs to, in
advance.
- Assign virtual LDEV ID to physical LDEV ID as well.
(Do not operate the physical LDEV ID to which the virtual
LDEV ID has not been set (Virtual LDEV ID will be FF:FE)
or the physical LDEV ID reserved for HA (Virtual LDEV
ID will be FF:FF))
