We are planning to upgrade FAS270 to FAS2050. According to our plan of action, we are going to convert the FAS270 to disk-shelf and adding it to FAS2050.Also we are going to assign all the 20 disks of FAS2050 to one of its node (e.g. node1) and the external disk-shelf (FAS270) will be added to the other node (e.g.node2). In node2 the root volume will be FAS270's root volume.
The thing I want to discuss is, on initial step we are going to up only one node of FAS2050 i.e. node1 and we will assign all the 20 disks to it. By keeping cluster disable. Later on when we will get downtime for FAS270, then we will convert it into disk-shelf and add to FAS2050.
Have anyone done this before? Or is there issue anyone faced??
Any suggestion will be appreciated. Thanks in advance.
