Operating Systems AIX hacmp in a 7 node configuration ?
# 8  
Old 08-30-2009
Hi Shockneck,

many many thanks for your reply. You have answered all my questions so far.
- DBAs don't have root access to the cluster
- only 2 SAs will have root access - me and my backup - and we will both build the cluster together
- we have a very strong change control in place and our documentation is pretty good
- we are aware this is no 24/7/365 solution - that is why we have an independant DR recovery site and a uat environment for testing
- the A1-A5 servers + 1 spare are running right now in a VCS cluster on AIX ... our engineering doesnt support it past 9/2010 - that is basically why we're going to move it to hacmp
- we will have almost a year for build and testing
- we have a weekend greenzone of 36 hrs for the environment and always patch all nodes in any cluster at the same time
- we will have hartbeat on disk on at least 2 different mini-devicegroups as you suggested

Once more thank you for all your suggestions - I will keep you in the loop if problems arise as I can see you don't have any major objection Smilie

Thank you in addition for the EMC bug tip - this explains why we have the problems on the 2 node clusters ... our SAN engineering is probably aware but has not yet certified the fix - I will ask them on monday for the fix.

Kind regards

cmviewconf

cmviewconf(1m)															    cmviewconf(1m)

NAME

       cmviewconf - view Serviceguard cluster configuration information

SYNOPSIS

       cmviewconf [-o output_file]

DESCRIPTION

       cmviewconf collects and displays the cluster configuration information, in ASCII format, from the binary configuration file for an existing
       cluster.  Optionally, the output can be written to a file output_file.

       This command can be used as a troubleshooting tool to identify the configuration of a cluster.

       To view cluster information, a user must be superuser(UID=0), or have an access policy of MONITOR  allowed  in  the  cluster  configuration
       file, or have a policy of PACKAGE_ADMIN in a package's configuration file. See access policy in cmquerycl(1m) or cmmakepkg(1m).

       NOTE:  When  this  command is run by an authorized user who is not the superuser(UID=0), only those entries that match the user running the
       command and the node where the command is run are displayed.

   Options
       cmviewconf supports the following options:

	      -o output_file Log configuration information to a specified output file.	If this option is not specified, the information  will	be
			     directed to stdout.

RETURN VALUE

       cmviewconf returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       To dump the contents of the binary configuration file to the file /tmp/viewconf.log:

	      cmviewconf -o /tmp/viewconf.log

       To dump the contents of the binary configuration file to the screen:

	      cmviewconf

       cmviewconf was developed by HP.
