Goal
Solution
 Confirm ZDLRA Services are online (First compute node)
 Cell cell attributes on the new cells (All new storage cells)
 Configure Flashcache (All new storage cells)
 Update Etc Hosts (All compute nodes)
 Update cellip.ora (All compute nodes)
 Create Celldisks and Griddisks (All new storage cells)
 Use Case 1: SAME DELTA Storage Expansion
 ZDLRA X8M + X8M Storage Cells 
 Confirm the new griddisks can be seen by kfod (First compute node)
 Add the new griddisks to the ASM diskgroups (First compute node)
 Check Rebalance (First compute node)
 Check storage_location size
 Update the db_recovery_file_dest to the new Storage Location
 Create RA_CF
 Increase the size of the RA_POOL tablespace
 Update the SL_sizing Table Using the API Call
 Get the size of the Storage Location as RASYS USER
 Validate the size of Diskgroup (+DELTA) to be added to the Storage Location
 Update the Storage Locations to include the new storage
 Confirm that the storage location has increased in size
 Update the throttle to update the config values
 Confirm the Storage Location Size 
 Use Case 2: New DELTA(n) Expansion
 ZDLRA X8M + X9M Storage Cells (3 or more cells)
 Confirm the new griddisks can be seen by kfod (First compute node) 
 Update the asm_diskstring to Include the New Diskgroup
 Create the new DELTA(n) ASM diskgroup
 Add the CATALOG griddisks to the CATALOG ASM diskgroup
 Check Rebalance (First compute node)
 Check storage_location size
 Mount the new diskgroup on the other compute nodes (All other compute nodes)
 Use API call to Change the value of db_recovery_file_dest_size parameter
 Create RA_CF
 Check the NEW value of db_recovery_file_dest_size parameter
 Increase the size of the RA_POOL tablespace
 Get current data files count in rapoolN (rapool, rapool2, rapool3, rapool4) and confirm value = 56* #of X8M cell 
 Confirm that there are two (2) DELTA Diskgroups
 Confirm the multi tbs layout value Is 1
 Confirm disk group number (X8 + X9) with value 2
 Get new diskgroup number and diskgroup name
 Get total cell count after adding X9 cells
 Get total target value from rapool_interim_view
 Cleanup the rapool_interim_table 
 Update rapool_interim_table
 Confirm 8 rows in rapool_interim_table
 Update rapool_interim_table with value got from very beginning
 Check the rapool_interim_table
 Create data file in DELTA2 for rapool, rapool2, rapool3, rapool4
 Check rapool_view
 Update the SL_sizing Table Using the API Call
 Get the size of the Storage Location as RASYS USER
 Update the Storage Locations to include the new storage
 Confirm the Expansion was Successful by checking the sizes for SL
 Update the throttle to update the config values
 Confirm the Storage Location Size
