Undocumented Celerra / VNX File commands

The .server_config command is undocumented from EMC, I assume they don’t want customers messing with it. Use these commands at your own risk. 🙂

Below is a list of some of those undocumented commands, most are meant for viewing performance stats. I’ve had EMC support use the fcp command during a support call in the past.   When using the command for fcp stats,  I believe you need to run the ‘reset’ command first as it enables the collection of statistics.

There are likely other parameters that can be used with .server_config but I haven’t discovered them yet.

TCP Stats:

To view TCP info:
.server_config server_x -v “printstats tcpstat”
.server_config server_x -v “printstats tcpstat full”
.server_config server_x -v “printstats tcpstat reset”

Sample Output (truncated):
TCP stats :
connections initiated 8698
connections accepted 1039308
connections established 1047987
connections dropped 524
embryonic connections dropped 3629
conn. closed (includes drops) 1051582
segs where we tried to get rtt 8759756
times we succeeded 11650825
delayed acks sent 537525
conn. dropped in rxmt timeout 0
retransmit timeouts 823

SCSI Stats:

To view SCSI IO info:
.server_config server_x -v “printstats scsi”
.server_config server_x -v “printstats scsi reset”

Sample Output:
This output needs to be in a fixed width font to view properly.  I can’t seem to adjust the font, so I’ve attempted to add spaces to align it.

File Stats:

.server_config server_x -v “printstats filewrite”
.server_config server_x -v “printstats filewrite full”
.server_config server_x -v “printstats filewrite reset”

Sample output (Full Output):
13108 writes of 1 blocks in 52105250 usec, ave 3975 usec
26 writes of 2 blocks in 256359 usec, ave 9859 usec
6 writes of 3 blocks in 18954 usec, ave 3159 usec
2 writes of 4 blocks in 2800 usec, ave 1400 usec
4 writes of 13 blocks in 6284 usec, ave 1571 usec
4 writes of 18 blocks in 7839 usec, ave 1959 usec
total 13310 blocks in 52397489 usec, ave 3936 usec

FCP Stats:

To view FCP stats, useful for checking SP balance:
.server_config server_x -v “printstats fcp”
.server_config server_x -v “printstats fcp full”
.server_config server_x -v “printstats fcp reset”

Sample Output (Truncated):
This output needs to be in a fixed width font to view properly.  I can’t seem to adjust the font, so I’ve attempted to add spaces to align it.

Domain Controller Commands:

These commands are useful for troubleshooting a windows domain controller connection issue on the control station.  Use these commands along with checking the normal server log (server_log server_2) to troubleshoot that type of problem.

To view the current domain controllers visible on the data mover:

.server_config server_2 -v “pdc dump”

Celerra Health Check with CLI Commands

1 Comment

Here are the first commands I’ll type when I suspect there is a problem with the Celerra, or if I want to do a simple health check.

1. <watch> /nas/sbin/getreason.  This will quickly give you the current status of each data mover. 5=up, 0=down/rebooting.  Typing watch before the command will run the command with continuous updates so you can monitor a datamover if you are purposely rebooting it.

10 – slot_0 primary control station
5 – slot_2 contacted
5 – slot_3 contacted

2. nas_server -list.  This lists all of the datamovers and their current state.  It’s a good way to quickly tell which datamovers are active and which are standby.

1=nas, 2=unused, 3=unused, 4=standby, 5=unused, 6=rdf

id      type  acl  slot groupID  state  name
1        1    0     2                         0    server_2
2        4    0     3                        0    server_3

3. server_sysstat.  This will give you a quick overview of memory and CPU utilization.

server_2 :
threads runnable = 6
threads blocked  = 4001
threads I/J/Z    = 1
memory  free(kB) = 2382807
cpu     idle_%   = 70

4. nas_checkup.   This runs a system health check.

Check Version:  5.6.51.3
Check Command:  /nas/bin/nas_checkup
Check Log    :  /nas/log/checkup-run.110608-143203.log

————————————-Checks————————————-
Control Station: Checking if file system usage is under limit………….. Pass
Control Station: Checking if NAS Storage API is installed correctly…….. Pass

…

5. server_log server_2.  This shows the current alert log.  Alert logs are also stored in /nas/log/webui.

6. vi /nas/jserver/logs/system_log.   This is the java system log.

7. vi /var/log/messages.  This displays system messages.
