Hello
I am a noobie to HACMP
I have 2 55A servers and a 7031 disk subsystem
For HACMP to work, do I need to have the hdisks on both servers to match the same drives??
The hdisks on each box are currently different:
hdisk0 and hdisk1 are the internal disks and hdisk2-5 are on the D24 on... (1 Reply)
Hi Guys,
I have two nodes clustered. Each node is AIX 5.2 & they are clustered with HACMP 5.2. The mode of the cluster is Active/Passive which mean one node is the Active node & have all resource groups on it & the 2nd node is standby.
Last Monday I noted that all resource groupes have been... (2 Replies)

sysdef
sysdef(1M) System Administration Commands sysdef(1M)NAME
sysdef - output system definition
SYNOPSIS
/usr/sbin/sysdef [-i] [-n namelist]
/usr/sbin/sysdef [-h] [-d] [-i] [-D]
DESCRIPTION
The sysdef utility outputs the current system definition in tabular form. It lists all hardware devices, as well as pseudo devices, system
devices, loadable modules, and the values of selected kernel tunable parameters.
It generates the output by analyzing the named bootable operating system file (namelist) and extracting the configuration information from
it.
The default system namelist is /dev/kmem.
OPTIONS -i Prints the configuration information from /dev/kmem. This is the default and only needs to be specified if the configura-
tion information from both /dev/kmem and the system file specified with the "-n namelist" option is needed.
-nnamelist Specifies a namelist other than the default (/dev/kmem). The namelist specified must be a valid bootable operating system.
-h Prints the identifier of the current host in hexadecimal. This numeric value is unique across all Sun hosts.
-d The output includes the configuration of system peripherals formatted as a device tree.
-D For each system peripheral in the device tree, display the name of the device driver used to manage the peripheral.
