Administrator Guide

This type of operation is not common, and you should consider your conflict resolution options carefully. To resolve this conflict,
do either of the following:
● If the pool conflict was expected—for example, you want to access data on the disk group from pool A of the old system:
1. Unmount and unmap the LUNs from any host accessing volumes on the new system.
2. Stop I/O from hosts accessing any volumes on the new system and power down the new system.
3. Physically remove all disks for the original pool A of the new system.
4. Insert the disks from pool A of the old system.
5. Restore power to the new system. The data on the disk group from pool A of the old system is now accessible.
6. Copy that data to pool B on the new system.
7. After you have copied the data to the new system, remove the disks from old system and reinsert the disks from the new
system.
8. Remap and remount the LUNs to any host that requires access to volumes on pool A of the new system.
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 52
● 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.
