Discussion ViPR SRM 3.6 - Configure EMC Secure Remote Support

The pool reserved capacty (PRC) along with the % subscription controls perform this function for you.

New allocations into the pool will fail when the threshold is exceeded.

If you set these parameters to your requirements, you will get what you are after in terms of preventing new provisioning into a pool that exceeds your defined limit.

The best would be to set the subscription limit to 100%.

Hi,

This discussion is to put up a message like " Do not subscribe ". So that any admin can understand by looking at the message or instruction put along with pool name and not bind any more devices to the pool.

Is there a way to put an instruction just like tag line along with title.

Hi Jas,

Let me know how to set PRC

Examine the subscription settings for the pool.

Get the pool name by running:

symcfg -sid XXXX list -pool -thin -gb -detail

Once you've located you pool name and observed the current subscription you then need to look at what is currently the maximum subscription:

symcfg -sid XXXX show -thin -pool $POOL_NAME -detail

Pipe it to a pagination utility such as 'more' or you can simply run a grep or a 'find /i ' on:

Max. Subscription Percent

Once you've got that number you can then set it to a point above what the current subscription is.

From there you'll need to run a config change that looks like this:

set pool $POOL_NAME max_subs_percent=n;

Where n = current subscription plus one.

The PRC setting does not affect new allocations, if only affects FAST VP movements into the pool.  The purpose of the PRC is to reserve a percentage such that FAST VP will not fill up the pool, such that there is space available in the pool for new allocations to be made.
