Run the script from an administrator command prompt window.

 PortErrShow output 

Frames tx/rx N/A
counters representing the number of frames transmitted

Enc_in
8bit/10bit encoding errors inside frame. Words inside of frames are encoded,
if this encoding is corrupted or an error is detected enc_in is generated.”
”Minimum compliance with the link bit error rate specification on a link continuously”
”receiving frames would cause approximately one error every 20 minutes.”
”Re-initialisation / reboots of the associated Nx-port can also cause these errors.”

Crc_err
crc errors – a mathematical formula generates counters at sending port,
receiving port uses the same formula to check and compare.
”Statistically, crc_err and enc_out errors together imply GBIC/SFP problem.”
”Also see “bad_eof” below.”

Too_long
FC frames are 2148 bytes maximum. Frames that were longer than the FC
maximum (SOF+header+2112bytes+CRC+EOF). If an eof is corrupted or data
generation is incorrect a too_long error is reported.

Too_short
The too_short error statstics counter is incremented whenever a frame,
bounded by an SOF and EOF, is received and the number of words between the SOF
and EOF is less than 7 words (6 words header plus 1 word CRC), i.e. 38 bytes (not 48)
including the SOF and EOF.
‘This could be caused by the transmitter, or an unreliable link.”

Bad_eof
After a loss of synchronization error, continuous-mode alignment allows
the receiver to re-establish word alignment at any point in the incoming bit stream
while the receiver is operational. If such a re-alignment occurs, detection of the
resulting error condition is dependant upon higher level functions (eg: invalid CRC,
missing EOF)

Enc_out
8bit/10bit encoding errors occurred in words (ordered sets) outside of the
FC frame. Words outside of frames are encoded, if this encoding is corrupted or an
error is detected enc_out is generated. It indicates a problem if it increments faster
than the link-bit error rate allows, approximately once every 20 minutes for 1 Gbit/s.
”Statisically, enc_out errors on their own imply a cable/connector problem.”<br>Enc_out”
”errors and crc_err together imply GBIC/SFP problem.”
”Such errors are also expected every time a user brings a port down and up (i.e. reboot”
”host, power-cycle storage subsystem, unplug/plug cable or portdisable/portenable”
”etc).Such errors will also be generated on a link which has a 1Gbit/s port connected”
”to a 2Gbit/s port when autonegotiation is turned off.”

Disc c3
Discard class 3 errors could be generated by switch when devices send
frames without FLOGIing first or with an invalid destination. This error is just
reporting that a discard occurred.

Link-fail
If a port remains in the LR Receive State for a period of time greater than a
timeout period (R_A_TOV), a link reset protocol timeout shall be detected which
results in a link failure condition (enter the NOS transmit state). The link failure also
indicates that loss of signal or loss of sync lasting longer than the R_ATOV value was
detected while not in the offline state.

Loss sync
Synchronisation failures on either bit or transmission-word boundaries are
not separately identifiable and cause loss-of-synchronisation errors.
”Such errors are also expected every time a user brings a port down and up (i.e. reboot ”
”host, power-cycle storage subsystem, unplug/plug cable or portdisable/portenable ”
”etc).”

Loss sig
Occurs when a signal is transmitted but none is being received on the same
port.
”Such errors are also expected every time a user brings a port down and up (i.e. reboot ”
”host, power-cycle storage subsystem, unplug/plug cable or portdisable/portenable ”
”etc).”

Frjt
If the fabric can’t process a class 2 frame a F_RJT is returned

Frbsy
If a fabric can’t deliver a class 2 frame within E_D_TOV frame will be<br>
discarded and a F_BSY returned

Newly installed P4330 Lefthand node does not want to join Management group

Today I had to add 2 P4330 nodes to an already existing P4300G2 management group.

Both P4300G2 systems and P4330 systems where on FW level 11.5.
When adding them to the management group an error occurred:

Storage system did not join the management group <GROUPNAME>.
Failed to sync newly added system. Remove the newly added system and try to add it again.

Als the system gave me following error:
“Storage System Status Missing”

Searching the internet I got to a page that indicated that there could be a subnet mask mismatch.
Checking this I came to the conclusion that all was OK. So the “SAN”switches, subnet mask, VLANning.
I made a call with HP.

Seems that some P4x30 systems with FW level 11..5 loaded from the factory have a BUG in the system that gives this result.

So please make sure, if you have this error, you do a Re-Image of the system (keep license key at hand) and re-do the settings you made earlier.
But this will solve your error.

Have Fun!

MSA1040 or MSA2040: Fan’s running full speed

We have had an installation of a MSA 1040 system. At the customer site, we discovered that the FAN’s kept running on full speed.

Current firmware was:  GL105P003

New firmware from HP (released 01 December 2014) fixes this problem (GL200R007).

Hopes this helps you all.

Cleaning Brocarde Switch Zoning

There are moments you need to get the old zoning out of a Brocade SAN switch. This could be, because you are re-using an older switch in your enviroment, or maybe you have been working on your fabric without noticing that you had a Fragmented Fabric.

To clean the config do following steps:

switchDisable
cfgDisable 
cfgClear 
cfgSave
switchEnable

.. and voila!!! A brand new switch.!

Manager count HP P4000

Looking for the best practice regarding the amount of managers that should be running in a Single Site config. I saw that this was not that easy to find (as HP is aiming on Multi-Site Clusters).

For a single site next does count.

2 Nodes, 1 FOM, 3 managers
3 Nodes, 0 FOM, 3 managers
4 Nodes, 1 FOM, 3 or 5 managers (5 preferred)

Just make sure you have an odd manager count, so 1 node can fail ad you still will have 2 managers running.
This could mean that you could run without a FOM in a 4 Node SS Cluster. (3 managers running on 3 Nodes, but nothing may go wrong when 1 node already has failed.)

Replace faulty disk in P2000 G3 without a spare configured

  1. Wait for the array to become healthy (not degraded).
  2. Add the replacement disk and configure it as a dedicated spare.
  • Physically pull the global spare and wait for the system to start using the dedicated spare disk.
  • Replace the global spare disk. It will show up as ‘leftover’ (LEFTOVR).
  • Clear the metadata on the leftover disk (Menu: top level: Tools: ‘Clear disk metadata’).
  • Re-add the disk as a global hot spare (Menu: Top level: Provisioning: ‘Manage Global Spares’).
