RE: When configuring GEfN, what is the maximum configuration distance between sites (for GAD and NAS respectively)?

The limits of the GEfN solution is governed by GAD - please feel free to read thru one of files on SupportConnect, one of which is the following:  https://docs.hitachivantara.com/v/u/en-us/disaster-recovery-solution/6.0.x/mk-97hdrs003 Until now, I know HIS hasn't been involved in a GEfN solution - ...

Hello Miran,  I'm sure one of you wonderful Global Delivery folks you've worked with could assist in this conversation, but I'm unable to tag them here for awareness. What they would tell you is that filesystems are no shrinkable and thus neither is a span. Below is an example of what I mean - there ...

RE: Does HNAS support other SAN storages? For instance Pure?

No it is not. HNAS supports Hitachi storage arrays exclusively. In bygone days (well over a decade ago, dating back to pre-Hitachi days of the product), the server supported 3rd party arrays - but they were thru OEM relationships and it wasn't just "any vendor".

The presumption you are making is that drive code on Seagate xxxx is the same for very vendor/OEM (which it's not). Most OEM's (including Hitachi) have specific code along with vendor identification in that code (so you can't insert a drive purchased off yahoo.com). Some vendors may not follow that mantra ...

These type of events are not uncommon and provide support/engineering insight into the system.

Hello Kwon, I see you listed in SalesForce and am copying my teammate @Namsoo Kim so he can work directly with you. Generally speaking filesystems should never become full, they usually auto expand - so your environments should be revisited. If/when a filesystem become full, it will not fail, but incoming ...

One of the mechanisms that can be used is the CLI command "fs-analyze-data-usage", but this command takes some time to execute, especially if the filesystem in question is on the larger side (there is not a definition of "larger"). Feel free to read the details on the man page. ------------------------------ ...

Venkatesvara, if you are experiencing a performance issue, please open a case with GSC and they will guide you in the investigation. You can generate a PIR (via the CLI, see the man page for 'pir') against the filesystem or node; PIR does not execute against ViVol nor are there metrics using ViVols. ...

We certainly hear and understand the need for non-NDMP based backup using snapshots. Many of our acct teams are aware of this need, for obvious reasons and the topic is making its way up the roadmap of priorities - but it is a heavy lift. D-NAS has been used but does not function in the manner that ...

Andy, I spoke to our HNAS global GSC lead and you presume correctly, FQDN would do it and help you out with option "C".

Your VSP G400 Unified platform does not go End of Service Life for another year+, but I do see your maintenance has not been renewed.  Because you have a Unified HNAS with embedded NAS modules, there is no "external loop", the ICC is internal to the "array". There is a hint in the output above, but ...
