IBM Elastic Storage System 5147-102 - Adding up to Four 5147-102 Storage Enclosures to an Existing ESS 3500 Hybrid Configuration; Hybrid Configuration

Example:
[root@ess3500rw6a ~]# mmlsfs all -B
File system attributes for /dev/fs3500hyper:
============================================
flag value description

-B 4194304 Block size
[root@ess3500rw6a ~]#
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>
d. Dene the appropriate number of vdisk sets for the HDD DAs (2 per 5147-102 enclosure).
# mmvdisk vs define --vs <vdisk set> --rg <recovery group> --code 8+2P --block-size
<block size> --set-size
<X>% --da <DA> --nsd-usage dataOnly --storage-pool <data pool>
e. Create the new vdisk sets.
# mmvdisk vs create --vs all
f. Add the vdisk sets to the lesystem.
# mmvdisk fs add --fs <fsname> --vs <vsname1a, vsname1b>
# mmvdisk fs add --fs <filesystem> --vs <vdisk set 1>,<vdisk set 2>
g. Recommendation: Restripe the lesystem as needed.
# mmrestripefs <fsname> -b
# mmrestripefs fs3500hyper -b
Adding up to four 5147-102 storage enclosures to an existing ESS 3500
hybrid conguration
This MES procedure involves adding up to four IBM Elastic Storage System 5147-102 Storage Enclosures
to an existing ESS 3500 hybrid conguration using single and dual adapter pairs.
Adding up to two 5147-102 storage enclosures using single SAS adapter pair
The hybrid conguration consists of one IBM Elastic Storage System 5141 - FN2 Server Enclosure and up
to four IBM Elastic Storage System 5147-102 Storage Enclosures.
