Changing settings for a host registered by using Device Manager agent
When the Device Manager agent is used, host information is periodically sentfrom the Device Manager agent. To update displayed host information, use
the Refresh Hosts button. Additionally, after changing settings on the Edit
Hosts dialog box, depending on which settings you changed, it may be
necessary to use Refresh Hosts to update host information.
To make changes or update host information to each item, see the followingtable:

Notes: 1. When copy pairs are managed by a host where Device Manager agent is installed, you need
to restart the Device Manager agent service after changing the host name. After the Device
Manager agent service is restarted, the new host name is applied by updating the storage
system.
2. WWNs/iSCSI names and their port types that have been added can be affected by the
Refresh Hosts button, but deleted WWNs/iSCSI names and their port types cannot beaffected. To delete such WWNs/iSCSI names, the Edit Hosts button needs to be used.
3. If you want to allocate volumes to a FCoE port, you need to manually add a WWN.
4. To update WWN nicknames that have been specified by using other storage system
management tools, such as Storage Navigator, refresh the storage system information. When
several WWN nicknames are assigned to a single HBA, only one of the nicknames is displayed
for that HBA.
Procedure
1. From the  Administration  tab, select Managed Resources .
2. On the  Hosts tab, select the host to update, then click either  Refresh
Hosts  or Edit Hosts  depending on the items that you want to update.

About removing hosts and releasing associated resources When hosts no longer need to be managed, for example due to areorganization, you can remove the registered hosts and exclude them from HCS management. Related storage resources, such as volumes allocated to
the target host and path setting information, can also be removed. However,
storage resources that are allocated to other hosts are not released.
When removing storage resources, you can select to:
• Unallocate volumes
• If the volumes that are unallocated when a host is removed are global- active device paired volumes, the following information is released at thesame time:
- Copy pairs
- Copy groups
- Configuration definition files (HORCM)
• Delete associated host groups/iSCSI targets • Release LUSE volumes• Delete virtual LDEV ID. This applies when managing resources that have virtual IDs set.
• Delete associated volumes
• Shred associated volumes. Format the volumes if shredding is unavailable.
By automatically executing these options as an extension of removing a host, the process is simplified.
Note:  When removing storage resources related to a host, verify that there is
not any related data remaining on the volumes.Discovering, registering, and adding management targets73Hitachi Command Suite User Guide 
						

							Tip: If you are removing a host that was registered using Device Manager
agent, uninstall the Device Manager agent from the host, then remove the host using HCS.Note:  If host information is synchronized between HCS and Compute
Systems Manager, the removal of hosts by HCS is not reflected in Compute
Systems Manager.

Registering file servers This module describes how to register file servers.
About registering and removing file servers You can register file servers to be managed by Device Manager so that the
volumes of the storage system can be used by the file server.
Device Manager manages file servers based on information sent from Hitachi NAS Platform family, Hitachi NAS Platform F, or Hitachi Data Ingestor.
Discovering, registering, and adding management targets75Hitachi Command Suite User Guide 
						

							Note: A system drive is the basic (logical) storage element managed by the
Hitachi NAS Platform family, and is equivalent to a storage system volume. Where volumes and system drives do not need to be differentiated, they are
generically and collectively referred to as volumes.
When a file server is registered you can:
• Allocate and unallocate volumes • Examine file server information• Determine the usage status of storage resources from the file server point of view
From Device Manager, you can activate the file server management software,
and change the settings of the file server or reference detailed file server
information.
From Device Manager, in addition to the operations above, and depending on
the versions of the file server management software that are linked and the
file server type, file systems can be created, shares can be added, and file
server reports and alerts can be viewed in the dashboard.
If the file server to be registered is Hitachi NAS Platform v10.2.3071 or later, use Device Manager to set the Admin services EVS information (the IP
address of Admin services EVS and the supervisor account information) after
the registration. This enables file systems to be created on Hitachi NAS Platform EVSs by using Device Manager.
If file servers become unnecessary for reasons such as reorganization, use file server management software to remove the settings for linking to Device
Manager, then remove the file servers from the file server list by using HCS.
The file servers are excluded from management by HCS, but configuration
information, such as the file system and file sharing created on the file server, and paths set during volume allocation, are retained.
For details about the system requirements of the file server, see the  Hitachi
Command Suite Administrator Guide .

Environment settings for Hitachi NAS Platform family To manage the Hitachi NAS Platform using Device Manager, the managementserver must be in a system configuration in which communication with SMU
and Admin services EVS can be performed.
The following diagram illustrates the network relationships between the
public management network and its connectivity with the NAS platform over
public IP addresses (SMU and Admin services EVS). The storage system connectivity illustrates the use of storage system volumes by the file server,
and File services EVS illustrates data services to clients over the public data network. Please see additional connectivity details below.
• Locate the management server on a network that can communicate with
SMU. To use the Device Manager GUI to create file systems for firmware
version 10.2.3071 or later of Hitachi NAS Platform, set up the system so that it can also communicate with Admin services EVS.
Discovering, registering, and adding management targets77Hitachi Command Suite User Guide 
						

							• Make sure that the version of SMU is the same or later as the firmwareversion of the file server (node).
• Make sure that the versions of the firmware for the file servers (nodes) in a cluster are all the same.
• If Device Manager is managing firmware version 10.2.3071 or later of Hitachi NAS Platform, register the following information for each cluster byusing the Device Manager GUI:
• IP address of Admin services EVS (Public management IP address 1 in the figure).
The IP address can be checked in the EVS Management page of SMU.
• User account for the Server Control (SSC). A supervisor account is set up as the default user.Note:  If you want to use the Device Manager GUI to check information
such as the system drive and storage pool information of the file server,
the file system information, or the sharing and exporting information, you
need to configure LUN security for the file server from the storage system
volume.

Registering file servers To register the file server (Hitachi NAS Platform family, Hitachi NAS PlatformF, or Hitachi Data Ingestor) as the resource managed by Device Manager,
specify the Device Manager information by using the management software on the file server.
If you register Hitachi NAS Platform version 10.2.3071 or later, specify the Admin services EVS information by using Device Manager. This establishes
linkage between Device Manager and the Admin services EVS software on the Hitachi NAS Platform.
Prerequisites
• In Device Manager, register the storage system that the file server uses.
• Set up the file server management software: ○System Management Unit (SMU) for Hitachi NAS Platform family
○ Hitachi File Services Manager for Hitachi NAS Platform F and Hitachi
Data Ingestor
• If the file server to be registered is Hitachi NAS Platform v10.2.3071 or later, gather IP addresses for Admin services EVS (a virtual machine that
manages the file server), and the user account for the Server Control
(SSC).

							Procedure1. Register Device Manager information by using the file server
management software.
Device Manager users that are specified in the management software of
the file server must belong to the  PeerGroup as a user group.
2. Additionally, if the file server to be registered is Hitachi NAS Platform
v10.2.3071 or later, perform the following steps from Device Manager to
set the Admin services EVS information:
a. On the  Administration  tab, select Managed Resources .
b. On the  File Servers  tab, select the Hitachi NAS Platform to be
registered, and click  Edit File Server.
c. Enter the Admin services EVS information, and then submit the task.
d. From the  Data Collection Tasks  tab, verify the task status.
Result File server information will be sent to Device Manager at regular intervals, and can be viewed in the File Servers tree on the Resources tab.Tip:  To remove registered file servers, use file server management software
to remove the settings for linking to Device Manager. Then select the file
servers to be removed from the HCS file server list in the Administration tab, and click Remove File Servers.

Changing the name of a file server You can change the file server name or IP address by changing theinformation registered in Device Manager, followed by changing the information on the file server.
Procedure 1. On the  Administration  tab, select Managed Resources .
2. On the  File Servers  tab, select a file server whose name you want to
change and click  Edit File Server.
3. Enter the new name for the file server using the format  file-server-
name @IP-address .
For Hitachi NAS Platform in a non-cluster configuration, if an IP address is not assigned to the node, enter the file server name in the following
format:
Discovering, registering, and adding management targets79Hitachi Command Suite User Guide 
						

							• If an IPv4 address is assigned to Admin services EVS: file-server-
name @IP-address-of-Admin-services-EVS .
• If an IPv4 address is not assigned to Admin services EVS:  file-server-
name .
4. On the file server side, change the file server settings on the target file
server.
5. If you are using System Management Unit (SMU) v10.2.3071 or later,
perform the following step:
a. In SMU, perform the operation to synchronize information between the
file server and Device Manager.Note:  If the file server name or IP address on the file server side does
not match the file server name ( file-server-name@IP-address) registered
in Device Manager, Device Manager cannot correctly recognize which file
server information has been sent when the information is sent from a file
server, and the same file server might be repeatedly registered under
different names. Therefore, file server information might not be updated
or an SNMP trap sent from the file server might not be displayed as an
alert. If a file server is repeatedly registered, you need to remove the file
server registered with the wrong name or an old name from Device
Manager.
