CAUTION: This type of operation must be performed offline. Removing a virtual disk group or pool while the
system is online may result in corruption and possible data loss. The system must be powered off before any
disks are removed.
• If the pool conflict was unexpected—for example, you did not realize that there was a previous pool on the disks of the old system
and data that is contained on the disks is no longer needed:
1. Remove the disks that were from the old system out of the new system.
2. Put the disks back into the old system.
3. From the old system, delete the pool off the disks.
CAUTION: Deleting a pool deletes all the data that it contains.
4. Reinsert the disks into the new system.
The disks from the old system now show as available and can be added to an existing pool on the new system.
If you are unable to find a pool with a duplicate name, or are unsure of how to safely proceed, download logs from the system, and contact
technical support for assistance.
Configuring system settings
Access the System Settings panel by doing one of the following:
• In the Home topic, select Action > System Settings.
• In the System topic, select Action > System Settings.
• In the Welcome panel, select System Settings.
The System Settings panel provides options for you to quickly and easily configure your system, including:
• Set the system date and time
• Manage users
• Configure controller network ports
• Enable or disable management interface services
• Change system information settings
• Set system notification settings
• Enable SupportAssist on page 49
• Change host port settings (if applicable)
Navigate the options by clicking the tabs located on the left side of the panel. Tabs with a red asterisk next to them are required. To apply
and save changes, click Apply, To apply changes and close the panel, click Apply and Close.
Set the system date and time
Use the Date and Time panel to change the storage system date and time that appears in the banner. It is important to set the date and
time so that entries in system logs and notifications have correct time stamps.
You can set the date and time manually or configure the system to use NTP to obtain them from an available network-attached server.
Using NTP allows multiple storage devices, hosts, log files, and so forth to be synchronized. The NTP value can be an IPv4 address, IPv6
address, or FQDN. If NTP is enabled but no NTP server is present, the date and time are maintained as if NTP was not enabled.
NTP server time is provided in the UTC time scale, which provides several options:
• To synchronize the times and logs between storage devices installed in multiple time zones, set all the storage devices to use UTC.
• To use the local time for a storage device, set its time zone offset.
• If a time server can provide local time rather than UTC, configure the storage devices to use that time server, with no further time
adjustment.
Whether NTP is enabled or disabled, the storage system does not automatically make time adjustments for Daylight Saving Time. You
must make such adjustments manually.

1. Perform one of the following to access the Date and Time options:
