Troubleshooting system tasks Verify the status of queued system tasks in Virtual Storage Platform G1000
storage systems that do not successfully complete within a reasonable
amount of time and troubleshoot as necessary.
Check the details of a system task that has not completed successfully.
System tasks cannot be restarted but system tasks can be suspended or
resumed.
Note:  This procedure is for troubleshooting problems for tasks related to
changing a storage systems configuration, not for update database tasks, which are recorded in the Data Collection Tasks tab.
Procedure
1. On the  Tasks & Alerts  tab, select All Tasks.
2. Check the task  Status column in the  System Tasks  tab to determine if
a task has completed.
3. To view task details, click  Manage System Tasks, select the storage
system where the task is registered, and click  OK.
4. Verify the task status and details by performing the following actions:
• When a task status is  Failed, click the link to view the reason. You
can correct the problem and submit the task again. Click  Delete
Tasks  to delete the task that failed.
• When a task does not complete, it might be that the task list contained more than the maximum number of tasks allowed (384). Toresolve this problem, click  More Actions > Enable Auto Delete .
When  Enable Auto Delete  is set, tasks are automatically deleted
after they successfully complete and exceed the maximum allowed number.
Managing tasks391Hitachi Command Suite User Guide 
						

							Note: HCS can manage many storage systems. Therefore you can
manage up to 100,000 tasks before the oldest tasks start getting
deleted. Because system tasks are created for VSP G1000 storage only, the system task list will display 384 tasks, including up to 128
tasks with a status of In Progress, Waiting, or Suspended, and up to
256 tasks with a status of Completed or Failed. Enable Auto Delete is
recommended.
• When a task does not complete, it can be that the storage system configuration changed. To diagnose this, check whether the Resource
Lock is displayed for a long time. If so, this can indicate that another program is still running. Wait until that program finishes and submit
the task again.
• When the percentage of progress for an ongoing task is slow to indicate a change, it can be that another task operation is in progress.Continue to check on the status of the task until it completes.

Monitoring managed resources and resolving alerts395Hitachi Command Suite User Guide 
						

							Monitoring storage resourcesYou can check the status of storage resources to detect problems and outputreports to a CSV or PDF file containing search results or configuration and
capacity information about storage systems, hosts, volumes, logical groups,
and other storage resources.
If you have the Tiered Storage Manager license, you can see the operationalstatus of storage resources from the Mobility tab and perform integrated operations to optimize data placement.
If you have the Tuning Manager license, you can analyze storage system
performance in the Analytics tab. You can identify whether the cause of a
performance problem exists in storage systems in response to inquiries from
the host and application administrators, and analyze whether storage
resources are being used appropriately.
If you have a license for both Replication Manager and Hitachi Tuning Manager, you can check the C/T delta performance of managed copy groups
from the UR Performance Analysis window of the Replication tab. This allows
you to analyze the cause of C/T delta degeneration and check how to resolve
problems.
This information can be used to migrate volumes or add DP pool volumes to
optimize storage resources. The following graphics illustrate the flow of monitoring and checking the status of storage resources. To check daily
operational status, inquiries from a host or application administrator, see the
following respective figures:
396Monitoring managed resources and resolving alertsHitachi Command Suite User Guide 
						

							In summary, you can:
• View summary information from the Dashboard tab. • Check alerts from the Tasks & Alerts tab or the dashboard.• Search storage resources from the Search box on the tabs bar. • Reference data migration information from the Mobility tab.
• Analyze performance from the Analytics tab. • Analyze Universal Replicator performance from the UR Performance Analysis window of the Replication tab.
Viewing information summaries This module describes how to view summary information for registered
storage systems and hosts.
About checking system status in the dashboard The Hitachi Command Suite dashboard shows a summary of tasks, alerts,
and activities of registered storage systems.
• Storage System Alerts:  A list of links for each registered storage system
or file server and the associated alerts. You can choose particular severity levels of alerts to be collected in the Storage System Alerts report by clicking the tool icon in the application pane. Note that SNMP trapsreceived from the file server are displayed as alerts. For details about how
to specify settings to receive SNMP traps, see the  Hitachi Command Suite
Administrator Guide .
• Datacenter Utilization - Physical capacities:  A bar chart that provides
volume capacity information for Open-Allocated, Open-Unallocated, Open-
Monitoring managed resources and resolving alerts397Hitachi Command Suite User Guide 
						

							Reserved, Mainframe, and Free volumes. This chart applies to all of the
managed storage systems, collectively. Because capacities are calculated based on actual volume capacities, the capacity of virtual volumes, such as
DP volumes, is not included.
• Failed HCS Tasks:  A list of failed HCS tasks submitted by you or other
users. Each item includes the task name, task type, and description for the
failed task. Clicking the Task column link for a task that you submitted
allows you to view task details, including error messages. You may not
view task details for tasks that you did not submit.
• Failed System Tasks:  A list of failed System tasks submitted by you or
other users. Each item includes the task name, task type, and description for the failed task. Clicking the Status column link for a task that you
submitted allows you to view the processing status.
• Top 10 Consumers:  A list of the ten hosts or file servers having the
largest combination of allocated physical and virtual storage capacity. For
file servers in a cluster configuration, if the file servers are being managed
by System Management Unit v10.1.3070 or later, or by Hitachi File Services Manager v3.2 or later, information is displayed by cluster.
○ The Capacity column reports (capacity of basic volumes + reserved
capacity of DP volumes).
○ The Used Capacity column reports (capacity of basic volumes + used
capacity of DP volumes).
○ File System Used Capacity indicates the file system space used by file
servers or hosts as (the total value calculated from File system Used %
for each volume).Note:  The File System Used Capacity is displayed only for hosts that can
collect information by using Host Data Collector or Device Manager agent ,
or for file servers.
This value cannot be collected for a virtualization server.
You can click host or file server links on the Resources tab to see volume details related to capacity, used capacity, and volume type. By reviewing
this capacity information, you can efficiently use storage resources and
determine whether to migrate data to DP volumes.
• Tier Residency:  A chart displaying the usage of hardware tiers for each
logical group. You can compare the operating information of a logical group and the usage of hardware tiers by checking whether the hardware
tiers for the logical group are configured appropriately. You can also select
logical groups whose configuration is to be displayed. Click the tool icon in the application pane to configure logical groups that display the usage
status of hardware tiers.
• The following file server reporting is available in the Hitachi Command Suite dashboard, when the file servers are registered in Device Manager:

							○Top 10 File Systems:  When HCS is linked with a file server (Hitachi
NAS Platform family, Hitachi NAS Platform F (HNAS F) or Hitachi Data Ingestor (HDI)), information about file systems that have a large
capacity usage rate or free area can be checked to see if there is
insufficient free space. By default, the allocated capacity usage rate is
displayed in descending order. Clicking the column header of other
items displays the top 10 file system information again, ordered by the
selected item. You can also change the items displayed by clicking the
tool icon in the application pane.
○ Top 10 File Server Storage Pools:  When HCS is linked with a file
server (Hitachi NAS Platform family), information about storage pools
that have a large capacity usage rate can be checked to see if there is insufficient free space. By default, the capacity usage rate is displayed in descending order. Clicking the column header of other items displays
the information again, ordered by the selected item.
○ Top 10 File System Snapshots:  When HCS is linked with a file server
(Hitachi NAS Platform F), information about volumes having a high capacity usage rate can be checked to see if there insufficient free
space.
○ File Level Tier Residency:  When HCS is linked with a file server
(Hitachi NAS Platform F), a graph is displayed for each file system tier, showing the usage status of the file systems and the volumes for file
snapshots. You can review the usage rate and the used capacity and
then expand the file system to increase free space and optimize the used capacity distributed among tiers. If you click the tools icon to start
Hitachi File Services Manager, you can review the policy settings on the
tiered file system.
