							Managing resource labelsThis module describes how to manage resource labels.
About managing resource labels User-defined resource labels can be assigned to volumes and DP pools.
Specifically, resource labels can be volume labels, or DP pool names.
Resource labels help you:• Search for volumes or DP pools
• Differentiate between listed volumes or DP pools • Confirm the correct resource is being acted upon
When searching resource labels, you can:
• Allocate volumes or DP pools • Edit volume LUN paths
Resource labels are assigned using:
• Device Manager • Storage Navigator
For storage systems where resource labels have already been configured
using Storage Navigator, you can apply (import) the resource labels to
Device Manager in a batch operation.
If Device Manager and Storage Navigator are both actively used, and HCS is the primary management software, labels assigned in Device Manager can be
applied (exported) to storage systems managed by Storage Navigator.
Volume labels can be assigned when creating or allocating volumes depending on their use for hosts or applications. For Virtual Storage Platform G1000, importing and exporting labels is unnecessary because the labelinformation from the storage system and the HCS labels will always match.
Note:  Due to differences between Device Manager and storage systems,
incompatible character type or string length issues will be reported with pop- up messages. Use the message to resolve resource label naming issues.Tip:  You can apply any current label to the storage system by specifying the
following settings:
• For volume labels, select Reflect current labels to the storage systems.
• For DP pool names, select Reflect this pool name to the storage system.

Importing storage system resource labels In an environment where storage system resource labels have already been
set using Storage Navigator, you can apply (import) the storage system
resource labels to Device Manager.
Note:  Applying storage system resource labels overwrites all the volume
labels and DP pool names in HCS for the selected storage system. For Virtual Storage Platform G1000, refreshing the labels is unnecessary because the
label information from the storage system to HCS will always match.
Procedure
1. On the  Resources  tab, from the list of  Storage Systems in the
application pane, select the storage system whose labels you want to
apply.
2. Click  Refresh Labels .
3. Select the resource labels to apply, and submit the task.

Managing WWNs by using nicknames This module describes how to specify, change or delete WWN nicknames.
About managing WWNs by using nicknames Each host bus adapter (HBA) has a unique World Wide Name (WWN)
identifier that consists of a 64-bit physical address. The purpose of specifying
366Managing storage system informationHitachi Command Suite User Guide 
						

							WWN nicknames is to easily identify accessible HBAs that are registered in ahost group.
If one HBA WWN belongs to multiple host groups, you can set a nickname inthe WWN information that is defined for each host group. WWN nicknames
that are specified for a host group can provide information about the I/O path (host, host port, fabric, or storage port) of volumes that are linked to the
host group.
During configuration of SAN fabrics and paths, the HBA WWN nickname helpsyou confirm physical configuration information. You can:
• Check the storage HBA WWN nicknames in the list of volumes. • Specify or change the storage HBA WWN nicknames related to the host.
• View the HBA WWN nickname to confirm that the host port of the path to which a volume will be allocated is appropriate.
• Change the storage configuration, such as replacing an HBA and specifying the nickname for the replacement storage HBA WWN that is registered inthe host group.
The following figure illustrates the WWN nicknames created using the host
name, slot number, and HBA port.
WWN nickname examples :
• (Host Name)_(Slot Number)_(HBA Port)
• (Host Name)_(Slot Number)_(Fabric Number)
• (Host Name)_(Slot Number)_(Fabric Number)_(Port Number)
There are two options for editing a WWN nickname that is defined in a host group:
Managing storage system information367Hitachi Command Suite User Guide 
						

							• Collectively edit the WWN nickname for all related host groups. When thisoption is selected, the WWN nickname is applied to all host groups that
have the same WWN.
• Edit the WWN nickname of an individual host group. When this option is selected, only the WWN nickname of the individual host group is changed.Tip:  If a nickname is set to a WWN by using a storage system management
tool, such as Storage Navigator, you can view the latest WWN nickname by
refreshing the storage system information. Also, if there are multiple WWN
nicknames set to the host groups on the storage system, only one WWN nickname for the port on the host is selected and displayed automatically.

Searching HCS resources This module describes using search to locate, work with, and report on
storage resources.
About searching HCS resources Search finds storage and host resources quickly and easily, and allows you to
work with the resources from the search results.
Search is useful for:
• Investigating and working with storage resources - for example, you can quickly find a host and allocate a volume to the host. Note that when you
click on a search results link, you will automatically go to the resource in
the Resources tab so you can work with the resource, or you will get more
detail on the item, as with volumes.
• Reporting on storage resources - for reporting, search results and related detail can be saved as CSV files using the Export to CSV button, or fromthe Actions menu. Note that CSV (comma separated values) files can be
opened by many spreadsheet applications for review or editing.
Search methods include:
• Keyword search - a search on user entered text. You can enter a full or partial text string and search specific fields related to storage resources,such as:
○ Storage Systems - search names, IP addresses, and serial numbers
Managing storage system information369Hitachi Command Suite User Guide 
						

							○Hosts - search names, IP addresses, iSCSI names and WWNs
○ Volumes - search volume IDs that match the keyword, or volume labels
○ Parity Groups - search parity group names
○ DP Pools - search IDs that match the keyword, and names
○ Logical Groups - search names or descriptions
• Criteria search - a search on attribute information, for example a volume search where the volume belongs to a RAID 5 parity group.
○ Criteria searches can be saved by the user, and optionally, shared with
others
○ Note that saving searches requires a Tiered Storage Manager license

Keyword search To perform a keyword search, locate the Search box on the upper right sideof the GUI. The search box is always visible.
Procedure 1. Enter a full or partial text string in the  Search box. A partial string will
generally produce more search results.
2. By default, all resources are searched when you press Enter. You can
narrow the scope of your search using the  down arrow, selecting
Search Keyword for , and selecting a specific resource to search on.
This executes the search and displays results. Each resource has an icon
that appears in the search box when it has been selected, and is the new
default resource.
3. The  Keyword Search  dialog box is displayed. If there are no search
results for an  All Resources  search or you entered a null string, you will
see a help message. A search on a specific resource with no results
displays a resources tab with no results listed.
4. When search results are displayed, click the resource name hyperlink to
go to the  Resources  tab for the resource. When viewing the detail pane
for the resource (for example, a list of volumes for a host) you can use the  Export to CSV  button (or Actions menu) to generate a resource
report for selected detail pane items (for example, all or some of the volumes for a host), or you can select detail pane items to perform anoperation (for example, selecting a volume and editing the volume label).
5. If the current search results do not meet your needs, or you want to run
multiple searches without closing the  Keyword Search dialog box, you
can repeatedly enter a new search string, and select the resource to
search. To perform a criteria search for storage resources, click the  More
Searches  button to start the Search dialog box.
