Either shutdown the controllers or perform a cf takeover\giveback scenario and insert the PAM\FlashCache cards.
Install the license with license add XXXXXX
Configure Flexscale with:
- flexscale.enable on (same value in local+partner recommended)
- flexscale.lopri_blocks off (same value in local+partner recommended)
- flexscale.normal_data_blocks on (same value in local+partner recommended)
- flexscale.pcs_high_res off (same value in local+partner recommended)
- flexscale.pcs_size 0GB (same value in local+partner recommended)
Let it sit for a few days and then evaluate your working set size during peak or daytime usage:
stats show -p flexscale-access –i 1 –n 100
This is where you might need some help. You will need to review the current usage, cache hit and cache misses over the period of time and determine if the working set of the data is too great for the currently installed PAM card. If it is then you back the normal data blocks to off, otherwise leave it as is. Odds are that leaving normal data blocks on will be fine. It is highly unlikely that you will need to enable lopri blocks.
