Hello and good day,

I will try to explain myself as much as I can:

 

In our environment we have a couple of VSP and we have in all of them the CMD devices, also we have a linux server where we have one horcm file for each VSP, each horcm file is configured in order to communicate with each VSP using the CMD device, from here everithing works great, we can start and shutdown instances with no problem, we use those horcm in order to get information such as pool details, etc.

 

We have 2 new VSP, same models and I want to create new horcm for each one, I just copy one of the instances and modify the service and the SVP IP, also I register the service in etc/services but Im not able to start the horcm files, any idea what could be wrong?

 

Ive read the CCI and Truecopy manuals but Im not able to figure out what could be wrong.

 

Any info will be much appreciate.

Thanks.

Hello

 

Do you have an example of your config file? Be sure to point it to the controllers and not the SVP.

 

Should look something like this:

 

HORCM_MON# ip_address service poll(10ms) timeout(10ms)localhost 11001 1000 3000 HORCM_CMD# dev_name dev_name dev_name\\.\IPCMD-<IP ADDY>-31001

 

EG:

HORCM_MON

# ip_address service poll(10ms) timeout(10ms)

localhost   11001  1000      3000

HORCM_CMD

# dev_name dev_name dev_name

\\.\IPCMD-192.168.1.1-31001

 

also please post any errors from the log file.

Thanks,

This is the horcm I try to start

 

 

[root@Servernameetc]# more horcm512.conf

HORCM_MON

#ip_address            service        poll(10ms)    timeout(10ms)

localhost         31512                1000             3000

HORCM_CMD

#dev_name              dev_name               dev_name

#/dev/sdb

\\.\IPCMD-Array-IP-31001

HORCM_LDEV

#dev_group     dev_name       Serial #       CU:DEV MU#

#################CLU_AUTH_INTEL_01#############################

 

HORCM_INST

#dev_group                             ip_address     service

[root@Servernameetc]#

 

 

I have one question, Do I have to map the CMD device to the server even if this is trying to reach using IP?

Hello

 

 

Sorry the site has been having endless issues. Sorry for the late reply.

 

If you're using IP command devices, you dont need to provision a volume. From that server can you SSH to the controller IP port 20522, and login?

 

Some things to check:

  • Also note, it's important that you have the Controller IP and not the SVP IP.
  • Are you using the Raidcom instance that is installed with the microcode installed on your array or a different version?
  • Also what array are you doing this on?

Thanks! Yes the solution was to point the HORCM to the controller IP and not to the SVP.

 

Really appreciate it.
