A netapp failover possibility...???
by ian.gardner＠vf.vodafone.co.uk 10 Sep '98

10 Sep '98

Hi, We have two netapp filers serving mainly static data (updated overnight) to several hp-ux clients. If one server fails we can swap the clients onto the other server by mounting and switching symbollic links. eg. on a client: /discs/data -> /netapp1/data If netapp1 fails we mount data from netapp2 and relink: /discs/data -> /netapp2/data Now this leaves processes hanging on the dead server which can be killed using fuser -k netapp1:/data. This is only necessary if memory/swap … [View More]

One gotcha is that if you leave a bad drive sitting in the shelf, and the system reboots, it could think the drive is a hot spare and allow it to be used again. I don't think this … [View More]

SUMMARY: "Calling all F630/FC-AL users"
by just me. 09 Sep '98

09 Sep '98

Well, its been a week, and as such I suppose time for a summary. Last week, I posted the following request for comments: If you are a NetApp F630/FC-AL user and have encountered any (especially recurring) glitches with interactions between the Fibre Channel host adapter and OnTAP, or recurring FC hardware failures I'd appreciate hearing from you. On the flip side, if you are a NetApp F630/FC-AL user and have seen perfect performance from your filer, I'd love to hear about it too. I … [View More]

I think our system goes into 'degraded' mode when no spare is present. I'm the degenerate. (some mail misaddresses running around.) > Not quite.

Is it true that when one HD goes bad, it will be reconstructed on the hotspare, but if you don't pull out bad HD and replace it within the 24 hours system will shutdown? What happens in a case if you have 2 hotspare? Thanks, --Leila.

OnTap
by Wm Kevin Shaw 08 Sep '98

08 Sep '98

What is the latest and most stable version of OnTap for a F630 (Non F-CAL)? What configuration issues and bugs should I be aware of? Any Info on configuring CIFS for this version of OnTap would also be appreciated. Thanks in advance. Kevin
