so what was the root cause for your problem?

Hi All,

My name is Amol, i have VNX gateway VG2 connected to CX-4 storage and assign LUN from CX4 storage, We have created server as data mover on VNX and after that created share folders also and shared  to the user.

   Now what happened we have unmapped block LUN from storage and bymistackly shares LUN's which are connected to VNX these are also get unmapped, now share path is not accessible to everyone we have mapped again to share LUN to VNX but no use, server last boot time is 3 years back. pleas help on this.

Hello Amol190,

When you remapped the Lun on your CX4, did you put all setting back as they were before? Which model VNX system do you have and what is the current OE that it is running? What is the current flare version of your CX-4 and which CX-4 system do you have?

@DELL-Sam L​  Hi We had  unmapped from CX4 and same mapped as it is to the host nothing setting has been changes everything has kept as it is.

Cx4 version V1.0.52.1.0073

VNX Control station: Release 3.0 (NAS7.1.79)

Hello Amol190,

When you look at your CX-4 is it showing as connected to your VNX or no?

yes, As i can see connectivity status is showing Active, please find the snap for the reference.

On cli getting below status

[nasadmin@srvsan01 ~]$ /nas/sbin/getreason

10 - slot_0 primary control station

0 - slot_2 reset

0 - slot_3 reset

Hello Amol190,

Have you verified that Datamover is fualted or online? Here is the command to run from CLI

[nasadmin@Mea ~]$ /nas/bin/nas_server -info -all

If your datamover is not showing faulted, then you will want to reboot your control station. If your data mover is showing as faulted, then it is best to open a support case so that we can assist in bring it back online.

As per the above command is not running i think it is in hung state,  we have control station and node 1 and node 2 also.

                              for the UDP destination port (incremented by each
                              probe, default is 33434), for the ICMP seq number
                              (incremented as well, default from 1), and the
                              constant destination port for TCP tries (default
                              is 80)
  -t tos  --tos=tos           Set the TOS (IPv4 type of service) or TC (IPv6
                              traffic class) value for outgoing packets
  -l flow_label  --flowlabel=flow_label
                              Use specified flow_label for IPv6 packets
  -w waittime  --wait=waittime
                              Set the number of seconds to wait for response to
                              a probe (default is 5.0). Non-integer (float
                              point) values allowed too
  -q nqueries  --queries=nqueries
                              Set the number of probes per each hop. Default is
                              3
  -r                          Bypass the normal routing and send directly to a
                              host on an attached network
  -s src_addr  --source=src_addr
                              Use source src_addr for outgoing packets
  -z sendwait  --sendwait=sendwait
                              Minimal time interval between probes (default 0).
                              If the value is more than 10, then it specifies a
                              number in milliseconds, else it is a number of
                              seconds (float point values allowed too)
  -A  --as-path-lookups       Perform AS path lookups in routing registries and
                              print results directly after the corresponding
                              addresses
  -V  --version               Print version info and exit
  --help                      Read this help and exit

Arguments:
+     host          The host to traceroute to
      packetlen     Specify an alternate probe packet length (default is 40).

Hello Amol190,

Based on the output, your system has not booted and is in a faulted state. You can try to reboot the system and capture the boot so that we can see what is going on.

Ok , Thanks for the update But if system is not comes up then what to do and it is not booted since 3.5 years, what you think it will comes up? No system is hung state no any commands are running:

PAO

As per the configuration we have 2 control station:

1./nasmcd/sbin/./cs_standby -failover - ------ On primary

2.Secondary will become primary and wait for secondary comes up.

suggest your input also

Which CS first we need to reboot and what command should we use, if CS not comes up then. Atleast one CS should be available if another will not comes up.

Hello Amol190,

It is hard to say if the system will come back without being rebooted for that long, and not knowing what errors are happening. You should have 2 control stations configured on your VNX. Here is a link to a kb that has the steps for rebooting a control station. https://dell.to/4cCpj48
