Hi

We have activated CBU for our DR site and it remains for 10 days. Now This
is nearing for expiration.

Is it possible to activate another CBU token without IPLing the LPAR ? Is
there a way to activate CBU dynamically ?

Hardware : z14 zr1

Hi

Will there be any grace period before it expires?

Re grace period. I believe its 2 days.

However, my personal knowledge is a bit rusty now. Try this manual:

I was going through the z14 Zr1 guide . I don't see about grace period for
CBU test Activation.

I am I missing something ?

Peter,

As I said, I am bit rusty on the actual T&Cs (over the years there have been some changes). The 2 days 'grace' period might related to CBU (for DR) rather than CBU Test. In both cases a warning is issued that that 'CBU' duration is going to expire. I myself don't have access to IBM's ResouceLink which should have the answers.

Regards

Parwez Hamid

CBU test activation is 10 days max for each test.
A CBU REAL ACTIVATION (you are in a DR situation) would be up to 90 days.

So to activate another test CBU. Does it require a POR ?

For the benefit of other members

Test CBU Activation gave me 10 days plus 2 days of grace period

Then I was able to activate another CBU without IPLing or POR

Thanks all and thanks especially to Parwez .

Multiple CBU records may be active at the same time. CBU resources can be activated, deactivated, or the activation level changed concurrently (from an LPAR perspective).
I assume you're using shared processors only and z/OS. Usually, from z/OS you may need to configure additional logical processors online to utilize more logicals from a given LPAR, or (recommended) configure logicals offline before physically deactivating resources, if the new number of physical processors in the shared processor pool would be less than the number of logicals online to any single partition.
You cannot extend the CBU resources *from a given record* beyond the grace period. The Capacity on Demand user's Guide for your hardware model is a good resource, e.g., regarding the grace period handling.
In general, there should be no reason for IPLing z/OS unless you had disabled DYNCPADD in your LOADxx, or you would be running out of the limit and you need to utilize more logical processors. z/OS subsystems are usually well prepared to deal with model changes.
