Hi All,
I am new to Hitachi Storage, so please forgive my ignorance :)
I have read a lot of manuals and articles about GAD and trying to create a simple procedure on how to create a GAD volume and assign it to a host group (ESXi servers), so I can use it on Windows Cluster.
But, it seems I have a smogasboard in my head.
We have G600 in 2 Data Centers - G600-DC1 and G600-DC2.
G600- DC2 has virtual storage machine, but not G600-DC1
I use only CCI, as Graphical interface proven to be not stable.
We have 2 Servers HORCM-DC1 and HORCM-DC2 to use CCI. HORCM-DC1 uses HORCMINST=0 in it Environmental settings and HORCM-DC2 uses HORCMINST=1
How to list all LDEVs in specific range, so I can choose free? do I have to list on both virtual storage machine and G600-DC2?
Create LDEVs:
for DC1: raidcom add ldev -pool 1 -ldev_id 02:14 -capacity 8000G
For DC2: do I have to create it on G600-DC2 and then on virtual storage machine? Do I create raidcom add ldev -pool 1 -ldev_id 02:13 -capacity 8000G, and then somehow map it to 02:14 on virtual storage machine to match G600-DC1?
How do I tell the difference, creating on G600-DC2 or creating on virtual storage machine? Do I switch between system variable HORCMINST=1 and HORCMINST=0 on G600-DC2?
Naming LDEV: Easy with G600-DC1
raidcom modify ldev -ldev_id 02:14 -ldev_name VDC-Prod_VDC01PCFIL01_0214
Do I name is on G600-DC2?
raidcom modify ldev -ldev_id 02:14 -ldev_name VDC-Prod_VDC01PCFIL01_0213
Do I name it on virtual storage machine?
Creating Device Group: Do I have to create device group on G600-DC1 and G600-DC2? not on virtual storage machine?
Creating a pair
Creating Host group
Assigning pair to a host group.
I can find all commands myself, but if someone could create a sequence, for me, please?
