To avoid this problem, usage rights must be restored

 

(using the -zoption) before failback.

-z<host>

Restore previously seized core usage rights to the nPartition

 

containing the specified host. Core usage rights must be

 

available in the GiCAP group or the command fails.

 

This option can be useful particularly when core usage

 

rights have been seized from systems running vPars,

 

because the restoration of core usage rights may be

 

necessary in order to be able to reboot the vPar, depending

 

on the vPars database definition and the allocation of usage

 

rights among the vPars. If this is a potential problem, the

 

restoration command must be performed before rebooting

 

any vPar within an nPar from which rights were seized.

-C<codeword>

GiCAP codeword application. This option allows the user

 

to apply a GiCAP codeword to a Group Manager system.

 

(This option cannot be used to apply an iCAP codeword

 

such as an RTU or TiCAP codeword.) For GiCAP sharing

 

rights codewords, first purchase the GiCAP codeword

 

from HP. The number of rights purchased must equal or

 

exceed the number of cores without usage rights for all

 

planned members for all groups managed by the Group

 

Manager. Next, retrieve the codeword from the HP Utility

 

Pricing Solutions portal and apply it to the Group Manager

 

system. Unlike iCAP codewords, GiCAP codewords are

 

generated for a specified partition on a Group Manager

 

system, and can only be applied to that partition. Like iCAP

 

codewords, GiCAP codewords are also generated in a

 

sequence and must be applied in the order they are

 

generated for the Group Manager partition. However,

 

GiCAP codewords are sequenced independently from any

 

iCAP codewords for the same complex, and can be applied

 

independently from any such iCAP codewords.

 

Application of the GiCAP codeword allows members to

 

be added to one or more GiCAP groups.

-Q

Make a standby GiCAP Group Manager the active Group

 

Manager for all group members. The new active Group

 

Manager attempts to contact all group members, informing

 

them that this system is the active Group Manager. The

 

new Group Manager also attempts to contact the previous

 

Group Manager to make it the standby Group Manager.

 

If the new Group Manager cannot contact a group member,

 

that group member will continue to be managed by its

 

current manager. This may result in the member not being

 

able to loan or borrow usage rights or it may result in a

 

split group. The current system becomes the active Group

 

Manager regardless of whether these attempted contacts

 

succeed or fail.

 

When attempting to contact all group members, the new

 

active Group Manager may find that it must establish SSL

 

communication with a member host. If so, it will prompt

 

for that host's root password so that it can exchange SSL

 

keys with the host (unless the -noption is also specified).

 

HP recommends that SSL communication between the
