management group, the group should be configured for
Network RAID 10 (two-way mirror) or higher. Network
RAID 0 volumes should be disconnected (logged off) from
the application servers. Rebooting the storage system will
cause all iSCSI sessions on that storage system to be
terminated and recovered to one of the remaining storage
systems in the cluster. Consequently, application I/O to
the volume may stop until the iSCSI session is recovered.
Consider upgrading during off-peak time (if possible) to
avoid application impact.
The actual time to upgrade a storage system or a
management group depends on the specific platform and
configuration.
Schedule time for the upgrade.

information to a file. Also keep the Storage System Support
Bundle. You will need these if you call Support.
IMPORTANT: To ensure desired system settings are retained after upgrading from version 8.5,
use Copy Configuration before upgrading. Storage system settings are not retained after upgrading
from version 8.5 to version 10.0 or later. In the case of storage systems in a management group,
one storage system in the group serves as the source for the settings that are applied to all the
storage systems being upgraded. Therefore, use the Copy Configuration function in a version 8.5
or earlier CMC to apply the desired settings to all the systems that will be upgraded.
The storage system settings that may be retained after upgrading to version 10.0 include settings
for the following features:
• Alerts, including Alert emails
• SNMP general settings and traps
• Remote log files
