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. Enter the WWID of your system. 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 10000000, 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 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 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: Group names are case sensitive. • 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.

Table 10 Possible causes and corrective actions when no array is found
(continued)
Corrective action
Possible cause
restart is complete, the array that lost communication
will not be visible.
3.
Verify that switch zoning is correct.
4.
Click
Discover
.
Enter the WWID of your system.
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 10000000, 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 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 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:
Group names are case sensitive.
•
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.
