- Glossary of terms
● date/time-range is optional and specifies the time range of data to transfer, in the format: start.yyyy-mm-dd.hh:mm.
[AM|PM].end.yyyy-mm-dd.hh:mm.[AM|PM]. The string must contain no spaces.
● filename.csv is the file that contains the data. Dell EMC recommends using a filename that identifies the system,
controller, and date.
get perf:start.2019-01-26.12:00.PM.end.2019-01-26.23:00.PM Storage2_A_20120126.csv
In FTP, wait for the message Operation Complete to appear. No messages are displayed in SFTP; instead, the get
command returns once the download is finished.
6. Quit the FTP/SFTP session.
Download a system heat map data
If requested by support engineers for analysis, you can download cumulative I/O density data, also known as heat map data,
from the system. To gather this data, access the storage system FTP/SFTP interface and use the get logs command with the
heatmap option to download a log file in CSV format. The file contains data for the past seven days from both controllers.
1. In the PowerVault Manager, prepare to use FTP/SFTP:
a. Determine the network-port IP addresses of the system controllers. See Configuring controller network ports.
b. Verify that the FTP/SFTP service is enabled on the system. See Enable or disable system-management settings.
c. Verify that the user you plan to use has FTP/SFTP interface permissions. See Adding, modifying, and deleting users.
2. Open a Command Prompt (Windows) or a terminal window (UNIX) and navigate to the destination directory for the log file.
3. Type:
sftp -P port controller-network-address or
ftp controller-network-address
For example:
sftp -P 1022 10.235.216.152 or
ftp 10.1.0.9
4. Log in as a user that has permission to use the FTP/SFTP interface.
5. Type:
get logs:heatmap filename.csv
where: filename.csv is the file that contains the data.
For example:
get logs:heatmap IO_density.csv
In FTP, wait for the message Operation Complete to appear. No messages are displayed in SFTP; instead, the get
command will return once the download is finished.
6. Quit the FTP/SFTP session.
Updating firmware
You can update the versions of firmware in controller modules, expansion modules in drive enclosures, and disks.
If you have a dual-controller system and the Partner Firmware Update (PFU) option is enabled, updating the firmware on one
controller causes the system to automatically update the firmware on the partner controller. If PFU is disabled, after updating
firmware on one controller you must log into the IP address of the partner controller and perform the firmware update on that
controller.
● Ensure that the storage system is in a healthy state before starting firmware update. If the health of the system is Fault,
the firmware update cannot proceed. You must resolve the problem specified by the Health Reason value on the System
Overview panel before you can update the firmware.
● If any unwritten cache data is present, firmware update will not proceed. Before you can update firmware, unwritten data
must be removed from cache. For more information about the clear cache command, see the Dell EMC PowerVault ME4
Series Storage System CLI Guide.
● If a disk group is quarantined, contact technical support for help resolving the problem that is causing the component to be
quarantined before updating the firmware.
