Viewing user information
The user panel in the banner shows the name of the signed-in user.
Hover the cursor over this panel to display the User Information panel, which shows the roles, accessible interfaces, and session
timeout for this user.
The

(monitor role) or to manage all users (manage role). For more information on user roles and settings, see Managing users.
Viewing health information
The health panel in the footer shows the current health of the system and each controller.
Hover the cursor over this panel to display the System Health panel, which shows the health state. If the system health is not
OK, the System Health panel also shows information about resolving problems with unhealthy components.
The
icon indicates that the panel has a menu. Click anywhere in the panel to display a menu to change notification settings,
save log data, and view system information.
Saving log data to a file
To help service personnel diagnose a system problem, you might be asked to provide system log data. Using the PowerVault
Manager, you can save the following log data to a compressed zip file:
● Device status summary, which includes basic status and configuration data for the system
● The event log from each controller
● The debug log from each controller
● The boot log, which shows the startup sequence, from each controller
● Critical error dumps from each controller, if critical errors have occurred
● CAPI traces from each controller
NOTE:
The controllers share one memory buffer for gathering log data and for loading firmware. Do not try to perform
more than one log saving operation at a time, or to perform a firmware update operation while performing a log saving
operation.
Save log data from the storage system to a network location
1. In the footer, click the health panel and select Save Logs. The Save Logs panel opens.
2. Enter your name, email address, and phone number so support personnel will know who provided the data.
The contact name value can include a maximum of 100 bytes, using all characters except the following: “ ‘ ` &
The email address can include a maximum of 100 characters., except the following: “ < > \
The phone number value can include only digits and no other characters.
3. Enter comments describing the problem and specifying the date and time when the problem occurred. This information helps
service personnel when they analyze the log data. Comment text can include a maximum of 500 bytes.
4. Click OK. Log data is collected, which takes several minutes.
NOTE:
In Microsoft Internet Explorer, if the download is blocked by a security bar, select its Download File option. If the
download does not succeed the first time, return to the Save Logs panel and retry the save operation.
5. When prompted to open or save the file, click Save.
● If you are using Chrome, store.zip is saved to the downloads folder.
● If you are using Firefox and have a download folder set, store.zip is saved to that folder.
