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):

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):

NDMP Stats:



To Check NDMP Status:

.server_config server_x -v “printstats vbb show”

CIFS Stats:

This will output a CIFS report, including all servers, DC’s, IP’s, interfaces, Mac addresses, and more.

.server_config server_x -v “cifs”

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”

To enable or disable a domain controller on the data mover:

.server_config server_2 -v “pdc enable=<ip_address>” Enable a domain controller

.server_config server_2 -v “pdc disable=<ip_address>” Disable a domain controller
