c. Verify all DAs have appropriate number of drives.
Note: You need to have either 52 or 102 drives if you are adding only one enclosure. When
installing two enclosures, each enclosure must have 102 drives.
# mmvdisk pdisk list --rg <recovery group> | grep -c DA<x>
Example:
[root@ems9 ~]# mmvdisk pdisk list --rg ess3500_ess3500rw6a_hs_ess3500rw6b_hs | grep -c DA2
102
[root@ems9 ~]# mmvdisk pdisk list --rg ess3500_ess3500rw6a_hs_ess3500rw6b_hs | grep -c DA3
102
[root@ems9 ~]#
d. Define the appropriate number of vdisk sets for the HDD DAs (2 per 5147-102 enclosure).
Note: The actual output varies depending on the number of enclosures and drives.
