Raid Manager Configuration Problem

[vjta]

Hi All,
Thanks in Advance!!

I want to configure Raid Manager with Continuous Access to replicate 2 XP Boxes Installed at 2 different sites.

I have installed Raid Manager to both end Hosts. My instance is also starting successfully.

In my environment Firewall is configured & I am accessing DR side host thru NAT IP

pls suggest the Raid Manager Configuration in firewalled network.

Thanks & Regards

You just need to make sure that the HORCM instances can talk to each other over IP thorugh the firewall. You can configure the ports that HORCM listens on in the HORCM_INST ection at the top of each HORCM file. Just provide the IP and port number to your network guys and ask them to open them for your servers and you should be fine.

Hi Nigel,
Thanks for ur quick reply but as per my networking team they already open ports at both ends as I already ask them to open port for UDP.

Can anyone suggest me the entries in horcm.conf files & explain me.

Thnaks & Regards

Hi,

RM Horcm.conf conf file best practices:

Hi,

I am getting this logs in my horcc log file:

CMDLINE : pairdisplay -g cdbms_test
13:54:15-92ea0-08457- Received signal(SIG=2)
COMMAND ERROR : EUserId for HORC[100] : root (0) Thu Feb 12 14:06:48 2009
CMDLINE : raidqry -r cdbms_test
14:17:04-184d0-25281- Received signal(SIG=2)

Ive not seen that error before. Does the userid that the RM commands are running under as well as the context the HORCM daemons are running under have correct permissions etc?

have you tried running the pairdisplay commands with -l (lower case "L") so that commands are issued only against the local instance (the instance configured with HORCMINST) and therefore not trying to communicate over the network to the remote instance.

Are you sure you dont have the HORCC_MRCF variable set.

Can you upload your HORCM files?

Can you also upload log files for the affected HORCM instance?

Can you list all HORCC and HORCM environment variables that are set and that they are all visible to the shell you are running your commands from.

Hi ,
>>> Does the userid that the RM commands are running under as well as the context the HORCM daemons are running under have correct permissions etc? <<<<

How to check this? I am running by root user.

I have exported HORCMINST only nothing else.

pairdisplay with -l gives proper o/p of local pair.

In My horcmn.conf file

#-------------------------For HORCM Monitoring-----------------------
HORCM_MON
#Ip_address service poll timeout
172.16.12.10 horcm100 3000 1200000

This looks a little strange to me -

Is the HORCM file you have uploaded HORCM100.CONF?

What is the name of the HORCM instance on the remote server (the HORCM instance it is communicating with over the network)?

The name of the local and remote HORCM instance should not be the same.

You have defined HORCM100 in the HORCM_INST and the HORCM_MON section.

The local HORCM instance should be named HORCM100 and the remote instance should named differently, something like HORCM101.CONF. You will need to do the configuration of the services file etc to reflect this.

So in your HORCM100.CONF file should look like this -

HORCM_MON
172.16.12.10 horcm100 3000 1200000
.......
....
HORCM_INST
cdbms_test 10.29.1.205 horcm101

On the other side your HORCM101.CONF file should look like this -

HORCM_MON
10.29.1.205 horcm101 3000 1200000
.......
....
HORCM_INST
cdbms_test 172.16.12.10 horcm100

Are your device names in HORCM100 and HORCM101 the same?

Hi nigel,
Thanks for ur valuable reply.
After doing the said changes,my issue is not solved.

if I give pairdisplay -l -g cdbms_test cmd

it gives me o/p but without -l it will take time & come out without any error.

Thanks & Regards

Can you upload (as attachments) both of your HORCM files as well as the HORCM logs from your servers?
