NS20FC both SP have problem
Hi
we have one NS20FC in our service that using it as block device and our servers mount EMC filesystem.
recently I saw the front fault led of Blade Enclosure, after that I try to connect to it but the management not response at all. I connect to NS20FC from serial cable, after login to nasadmin user system show:
[root@NS20 ~]# su - nasadmin
*** slot_0 control station ready ***
EMC NAS Service is not running due to one of the following reasons:
1. EMC NAS Service is still starting or there was an error during
service start-up.
Please logout and try logging in after 5 minutes. It can take up to
15 minutes after Control Station boot for EMC NAS Service to start.
If the problem persists after 3 login retries, please reboot the
Control Station and try again. If this message is still displayed,
contact EMC Customer Support.
2. EMC NAS Software upgrade is in progress, which required stopping
the Service temporarily.
Please DO NOT use the administrative interface while EMC NAS Software
upgrade is in progress. EMC NAS Service starts automatically after
the upgrade finishes.
Until EMC NAS Service starts, administrative commands and interfaces
will not operate
I try getreason script, and the result is :
[nasadmin@NS20 ~]$ /nasmcd/sbin/getreason
6 - slot_0 control station ready
0 - slot_2 reset
19 - slot_3 general POST error
how can I reboot slot_2 and slot_3?
how can I be sure that there is no hardware problem?
Greetings,
Sorry, it is unlikely to be as simple as that. The state that the NASDB is in will mean that some community support intervention is going to be required. For example, if my suspicion is correct, the DM in slot_2 is probably reconfigured as a standby called "server_2.faulted.server_3" following the historical DM failover to slot_3. You need NAS service running for this.
If slot_2 is responsive, then try to execute a PXE reboot of the DM. Again, from your first message, it looks like the DM in slot_3 has a hardware fault which means it can't get beyond the Power On Self Test (POST), so that will need to be replaced, at the very least. I understand that you may not have access to Support for that.
There are many articles in the EMC Knowledgebase discussing how to recover DM's, via PXE boot, to get NAS service running. Try starting with http://support.emc.com/kb/73861

Greetings,
That indicates that server_3 has a hardware fault which it can't recover from.
Also, because server_2 is in a"reset" state that indicates that it failed over to server_3 at some point in the past. Normally, server_2 runs as Primary wit h server_3 as Standby.
It looks like you gave two faulted Data Movers, hence no NAS service is running, hence the message from the Crontrol Station.
You need to open a Service Request with EMC Support.
