PowerStore File services
I am confused about below statement about PowerStore File services.
File services only run on the primary appliance. In a multi appliance Cluster, if the primary goes down, the Primary Control Path services will fail over and a new Primary will be selected. File services (SDNAS) will NOT fail over. File services will be down until the old Primary is brought back online. When the old Primary is brought back online, file can be used again. The Primary Control Path services will not failback – they will remain on the new Primary
If primary appliance had malfunction, until it comes back the file system will not be accessed by client? Is that right? or it saying filesystem will be accessible via redundant node or appliance, but management task can't be? Please advise me to understand this better.
Thanks!

Hi,
Could you share where you saw this?
There are many components to this and I think it may be clearer if we separated them out.

Hi chenw87,
In the "PowerStore Configuration" training guide (pg 108) it states:
"
NAS deployment is only available on the master appliance in the PowerStore T multi-appliance cluster with storage locality restricted to the hosting appliance.
"
"Supports only manual failback of NAS server after node recovery." pg 130.
I've got to admit, that like tsamuel090590, I too had read that as meaning the whole NAS would be offline. Until reading your reply I hadn't taken into consideration in this scenario that the appliance is two nodes.

Thanks, Simon.
Yes, it is definitely important to remember that:
