○ crash1, crash2, crash3, or crash4: One of the Storage Controller’s four crash logs.
○ ecdebug: Expander Controller log.
○ mc: Management Controller log.
○ scdebug: Storage Controller log.
● filename is the file that contains the transferred data. Dell EMC recommends using a filename that identifies the system,
controller, and date.
get managed-logs:scdebug Storage2-A_scdebug_2011_08_22.zip
In FTP, wait for the message Operation Complete to appear. No messages are displayed in SFTP; instead, the get
command returns once the data transfer is finished.
6. Quit the FTP/SFTP session.
NOTE: The log files must be extracted from .zip file to view them.
Downloading historical disk-performance statistics
You can access the storage system’s FTP/SFTP interface and use the get perf command to download historical disk-
performance statistics for all disks in the storage system. This command downloads the data in CSV format to a file, for import
into a spreadsheet or other third-party application.
The number of data samples downloaded is fixed at 100 to limit the size of the data file to be generated and transferred. The
default is to retrieve all the available data (up to six months) aggregated into 100 samples. You can specify a different time
range by specifying a start and end time. If the specified time range spans more than 100 15-minute samples, the data will be
aggregated into 100 samples.
The resulting file will contain a row of property names and a row for each data sample, as shown in the following example. For
property descriptions, see the topic about the disk-hist-statistics basetype in the Dell EMC PowerVault ME4 Series
Storage System CLI Guide.
"sample-time","durable-id","serial-number","number-of-ios", ...
"2012-01-26 01:00:00","disk_1.1","PLV2W1XE","2467917", ...
"2012-01-26 01:15:00","disk_1.1","PLV2W1XE","2360042", ...
...
Use a command-line-based FTP/SFTP client. A UI-based FTP/SFTP client might not work.
Retrieve historical disk-performance statistics
Perform the following steps to retrieve historical disk-performance statistics:
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 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 go 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 perf:date/time-range filename.csv
where:
158
