Details of DSM Timer counter (path checking period, enable path checking,
number of retires, retry interval, PDO deletion period)
Details of MPIO paths Path status
3.8 Server Startup Notes
Before turning the server on, check that the ETERNUS DX storage systems are all "Ready". If the server is
turned on and they are not "Ready", the server will not be able to recognize the ETERNUS DX storage systems.
Also, when the ETERNUS DX power supply is being controlled by a UPS power supply linkage, make sure that
the ETERNUS DX is never turned off before the connected servers. If turned off, data writes from the running
server cannot be saved to the ETERNUS DX storage systems, and already saved data may also be affected.
3.9 System Design Sheet Notes
The system design sheet is a spreadsheet program work sheet that is used to simplify the process of instal-
ling the ETERNUS DX. It is important that the system details be recorded after first installing the system and
also each time the system is subsequently modified, expanded, or has maintenance work performed on it.
Creating a system design sheet makes installation and maintenance of the system easy.

3.10 Notes about Connections with a Windows Server®
When Windows Server® and the ETERNUS DX S4/S3 series are connected and Windows Server® is rebooted
after a firmware is applied to the ETERNUS DX S4/S3 series, the status of the disks on Windows Server® may
become offline.
The status of the disks on Windows Server® can be checked with the following procedure.
Click the [Start] button, select [Computer Management] under [Administrative Tools] and then select [Man-
age Discs] (or [Disk Management]) in the left pane.
Note that the occurrence condition and the workaround differ depending on the path configuration of Win-
dows Server®.
For single-path configurations, change the SAN Policy setting before a firmware is applied to prevent the disk
from becoming offline after the firmware is applied.
For multi-path configurations, there is no workaround. The procedure in "● Measure to take after a problem
occurs" (page 15) must be performed to recover from the offline status.
■Single-path configuration
The offline status can be avoided only when updating the firmware by changing the SAN Policy setting to
"Online All".
If operations are possible with the SAN Policy setting set to "Online All", Step 4 in "● Method for proactively
preventing occurrences" (page 13) is not required.
●Checking the SAN Policy setting
The following shows how to check the SAN Policy setting.
1Execute the "diskpart" command in the command prompt.
The prompt changes to DISKPART.
2Enter "san" and press the [Enter] key.
DISKPART> san
3One of the following SAN Policies appears.
•"Offline Shared"
•"Offline All"
•"Online All"
4Enter "exit" and press the [Enter] key to complete the "diskpart" command.

■Multipath configuration
The server starts up with the same disk status (online or offline) as when the multipathing was set up re-
gardless of the SAN Policy setting.
•When the multipathing of an online disk is set up during the configuration of the environment
The multipath disk starts up in the online status after the firmware is updated.
•When the multipathing of an offline disk is set up during the configuration of the environment
The multipath disk starts up in the offline status after the firmware is updated.
●Method for proactively preventing occurrences
For multi-path configurations, there are no proactive measures (such as a setting change) to prevent the disk
from becoming offline after the environment is configured. In addition, the disk status when multipathing
was set up cannot be checked after the environment is configured.
Perform the procedure in "● Measure to take after a problem occurs" (page 15) if the disk becomes offline
while the firmware is updated.
●Measure to take after a problem occurs
•When the OS can be started up
Manually change the offline disks to online by following the procedure below.
1Click the [Start] button, select [Computer Management] under [Administrative Tools] and then select
[Manage Discs] (or [Disk Management]) in the left pane.
2Select each offline disk, then right-click the selected disk to change the status to online.
•When the OS cannot be started up
If the Active Directory database is located in a disk other than the OS area, the OS may not be able to start
up because the disk is offline and the OS cannot access the Active Directory database.
In this case, the disk can be recovered by starting the OS in the Directory Services Restore Mode and chang-
ing the disk status to online.
The procedure for restoring (or reconfiguring) the disk is as follows:
1Start the server.
2Press the [F8] key on the server start-up screen.
3The Advanced Boot Options screen appears.
4Select Directory Services Restore Mode.

8Restart the OS.
If a firmware update of the ETERNUS DX is performed in a Hyper-V environment where a pass-through disk
is configured for the guest OS, the disk is recognized as a new disk and the pass-through disk is removed
from the physical hard disk. Therefore, the pass-through disk must be manually reconfigured to be re-
stored.
The procedure for restoring (or reconfiguring) the disk is as follows:
1Start "Hyper-V Manager".
2Select the offline guest OS and click [Settings] in the right pane.
The settings pop-up for the guest OS appears.
3In the settings pop-up under [SCSI Controller], select the hard drive that has the message "Physical

3.11 Notes for Formatting a LUN of the ETERNUS DX from a Win-
dows Server®
If a LUN of the ETERNUS DX is formatted from a Windows Server®, the following problems may occur.
•The formatting operation takes longer to complete.
•If the formatting operation is canceled, the canceled operation becomes unresponsive.
These are the problems caused by performance degradation due to the command being issued to release the
storage capacity for the entire formatting area.
Performance degradation can be prevented by executing the following command to change the parameter
value to stop the command from releasing the storage capacity of all the volumes.
# fsutil behavior set disabledeletenotify 1
After all formatting operations have been completed, execute the following command to re-enable the com-
mand that releases the storage capacity of all the volumes.
# fsutil behavior set disabledeletenotify 0
