Set a Storage Domain as the Primary
Circumstances can arise in which you might want to transfer the Persistence
VLUN, which contains the system configuration data, from the current primary
Storage Domain to a different domain.
Prerequisites:
● A non-primary Storage Domain.
● The following lists the minimum recommended number of Bricks in the
order of preference:
Note: If you have more than one Storage Class in the non-primary Storage
Domain, the Pillar Axiom storage system migrates to SATA, if that class is
available. If SATA is not available, the system migrates to FC, if that class
is available. If SATA and FC are not available, the system migrates to SSD.
When the non-primary Storage Domain becomes the primary domain, the
previous primary domain loses its primary status and the system migrates the
system data to the new primary domain. The administrator cannot cancel this
special data migration.
1 From the Configure tab, click Groups > Storage Domains.
2 Highlight the Storage Domain that you want to become the new primary
domain and choose Actions > Set as Primary Storage Domain.
3 To set the non-primary Storage Domain as the new primary domain, click
OK.
Result:
The systems begins migrating all system configuration and persistence data
to the new primary domain.
Important! After you click OK, you cannot cancel this data migration.
