| i could have a physical box which could contain different virtual box with different ip address and hostnames. in addition, i can have the ability to have clustering enabled so that its high available also known as hacmp. finally, there is a control workstation which controls all these virtual boxes. so far am i right? one last note... in a given hostname, i have a ip address. now, i also noticed that i could identify these different boxes through " a name " that i think its identified by the control workstation. and further analysis shows that they could be network interfaces. that is to say that i could direct the kind of transfer rate (example, rcp) by specifying the name/ip that is found in ifconfig -a. am i right? thanks |

If you have a control workstation, then you have a SP or SP2. These are physical boxes inside a frame controlled by the CWS. You wil have multiple IP addresses and hostnames in each of these physical nodes. If you have virtual boxes, with different hostnames and IP address, then you have a system that has Power 4 processors and the HMC (Hardware Management Console) controls this. What is the output of "lsattr -El sys0 -a modelname" HACMP can run on just about every model of pSeries/RS6000. > one last note... in a given hostname, i have a ip address. now, i also > noticed that i could identify these different boxes through " a name " > that i think its identified by the control workstation. and further > analysis shows that they could be network interfaces. that is to say > that i could direct the kind of transfer rate (example, rcp) by > specifying the name/ip that is found in ifconfig -a. > > am i right? > > thanks ifconfig -a only shows the name of the network devices and the support IP address. A unix system (including) AIX can only have one hostname, although it is possible in /etc/hosts or DNS to have a hostname for each network interface. e.g. wibble 192.168.0.1 \ wibble01_en0 192.168.1.1 ¦== These are all network adapters on the same machine wibble01_en1 192.168.2.1 / Steve |

Somewhat of a simplification, but a qualified yes. The POWER4 pSeries systems utilize logical partitioning and the hypervisor. There are a number of types of partitioning - dynamic, afinity, etc. But simplified, logical partitioning, or LPAR, allows one to divide a physical box into multiple partitions, each partition is capable of having dedicated CPU, memory and I/O resources associated with it. Each partition is also assigned one or more ethernet adaptors and these have their own IP addresses and host names. From an "end user" perspective an individual LPAR can look like a dedicated pSeries server in its own right. So a 32-way, 256Gb p690, with the appropriate hardware configuration, can be LPAR'ed into - say eight 4-way, 32Gb partitions - and will appear like eight separate servers to the user community. Of course - the above is a POWER4/AIX 5.2 discussion - there are a whole bunch of interesting things that come to light with POWER5 and AIX 5.3..... > known as hacmp. finally, there is a control workstation which controls > all these virtual boxes. The hypervisor is a Virtual Machine Monitor - it essentially sits between the OS/partitions and the hardware. The hypervisor is the mechanism by which the LPARs are controlled. The hypervisor is configured and manipulated via a separate entity called the HMC -- what I think you are referring to as the "Control Workstation" > with different ip address and hostnames. in addition, i can have the > ability to have clustering enabled so that its high available also Be carefully, clustering does not necessarily imply High Availability (HA) and vice versa. Just because you have a cluster does not mean that you have an HA solution. HA can be implemented as active-active, active-passive, etc. HA solutions are made up of a number of components including clustering (where appropriate). IBM provides the eServer 1600 which is the name of the pSeries Clustered solution. IMHO the eServer equivalent to the older SP technology. The 1600 is essentially built from pSeries servers such as the p6M2, p690 with high speed interconnect fabric and each node in the cluster runs a copy of the OS. There are clustering tools that then are incorporated into the solution. You can build an HA environment using a cluster or alternatively, you can build an active-passive HA solution using two (or more) non-clustered pSeries servers. Regards, Edward |

My experience of this is with IRIX not AIX -- so I may be wrong about AIX Regards, Edward |
