fix: connect disks pre-emptively during startup (#10669)

connect disks pre-emptively upon startup, to ensure we have
enough disks are connected at startup rather than wait
for them.

we need to do this to avoid long wait times for server to
be online when we have servers come up in rolling upgrade
fashion
