Creating Disk Groups With Double Protection Level; Security Credentials Configuration; Upgrading The Disk Drive Firmware - HP EVA P6000 Software Manual

Table 12 Possible causes and corrective actions when no array is found (continued)
restart is complete, the array that lost communication
will not be visible.
An array may not be visible to HP P6000 Command
View because the controllers are waiting for you to
enter the World Wide ID (WWID). This condition
occurs if the arraywas uninitialized and the rack is
power cycled.
This can also occur if back-end problems are
preventing access to the quorum drives. Once
communication is restored, you can re-enter the WWID
and the checksum.

Creating disk groups with double protection level

When creating a disk group with double protection level on an array running XCS 10001000, a
minimum of 10 disks is required on the array. If the disk group contains fewer than 10 drives and
double protection is requested, only single protection level will be used.
If all the physical disks in the disk group are of the same capacity, double protection level is
achieved by reserving capacity equal to more than four times the capacity of a single disk. If the
physical disks in the disk group are of different capacities, double protection is achieved by
reserving capacity equal to more than the sum of the four highest capacity disks.

Security credentials configuration

The following Windows-based security groups are required on the management server:
HP Storage Admins— This security group is required on the management server to enable
access to all features of HP P6000 Command View and must have at least one member (user
account). Members have view and manage capabilities.
NOTE:
HP Storage Users—Members have view capability only. This security group is required only
when a group with extremely limited use of HP P6000 Command View is needed.
Access control
Access authentication proceeds as follows:
1. The user's security group is checked to control access to various functions and web pages
used with HP P6000 Command View.
2. If the user belongs to the HP Storage Admins group, access is granted.
3. If the user belongs to the HP Storage Users group and the web page allows access to users
with the View HP Storage privilege, access is granted.
4. If the user belongs to the HP Storage Users group and the web page does not allow access
to users with the View HP Storage privilege, access is denied.
