In the HMC profile, I can see there are 3 physical FC assigned to the server as attached.
I also see 6 FC ports which is equivalent from 3x2=6
Exactly. Look at the "location codes" which i have marked bold:
fcs0 and fcs1 are port 0 and 1 from the same adapter, etc. for the others. In the HMC display you posted you see the "real" (physical) location codes where the adapters are located in the system. I.e. one adapter is located in the CEC with serial number 9K83854 in slot P1-C5.

Yes, absolutely. The reason for the VIOS is this: you have some "anonymous" resources like memory and CPUs which you can easily transfer between LPARs. You cannot do this with adapters, obviously, because they are connected to something and they are configured on the "outside" too. Neither you can do that with disks because they contain data which makes them the opposite of "anonymous". Therefore there is the VIOS, which takes all the physical ressources, creates virtual constructs representing these and then gives these constructs to the LPAR. This way you can move an LPAR from on managed system to the other because VIOSes ahve special means to transfer the physical layer between one another and for the LPAR the virtual construct it uses never changes - just the way it is representing some physical ressource.
Hi,
Is there a way to dynamically increase the size of virtual disk on the LPAR. The virtual disk is coming from my VIO Server. From my SAN I have allocated a disk to VIO Server and from VIO Server to my LPAR....If I increase the space of the logical SAN DISK (DS 4700 using IBM TotalStorage... (0 Replies)
Hi,
I want to know if there is any command which will tell me if an AIX machine is a LPar or not. I am using "lparstat -i" but it does not work on all AIX machines. Is there any generic command by whose output I will come to know if it is an LPar or not?
Please help.
Thanks,

Hello, we have a wierd and urgent problem, with a few of our p595 LPARs running AIX 5.3. The LPARs ran AIX 5.3 TL 7 and booted off EMC SAN disks, using EMC Powerpath. Every boot we run "pprootdev on" and "pprootdev fix". We can issue "bosboot -a" and we can reboot the machines.

Hi Guru, my question is that can I create LPAR in AIX 5.3, 6.0, 6.1 by using smit lpar, rather than using HMC or AIX Commands? Thank you very much. Mir Alihttp://xwww.unix.com/images/icons/icon5.gif (3 Replies)
I have login into a server, and when i launch this command uname -L.
I can see there is a LPAR.
But is there anymore commands i can use to get more information on the LPAR ?
like it is VIO ?
wat the IP address ?
etc, etc.
please help. Thank you. (7 Replies)

ARCMSR(4) BSD Kernel Interfaces Manual ARCMSR(4)NAME
arcmsr -- Areca Technology Corporation SATA/SAS RAID controller
SYNOPSIS
arcmsr* at pci? dev ? function ?
DESCRIPTION
The arcmsr driver provides support for the PCI-X and PCI Express RAID controllers from Areca Technology Corporation:
- ARC-1110 PCI-X 4 Port SATA RAID Controller
- ARC-1110ML PCI-X 4 Port SATA RAID Controller
- ARC-1120 PCI-X 8 Port SATA RAID Controller
- ARC-1120ML PCI-X 8 Port SATA RAID Controller
- ARC-1130 PCI-X 12 Port SATA RAID Controller
- ARC-1130ML PCI-X 12 Port SATA RAID Controller
- ARC-1160 PCI-X 16 Port SATA RAID Controller
- ARC-1160ML PCI-X 16 Port SATA RAID Controller
- ARC-1170 PCI-X 24 Port SATA RAID Controller
- ARC-1200 Rev A PCI Express 2 Port SATA RAID Controller
- ARC-1202 PCI Express 2 Port SATA RAID Controller
- ARC-1210 PCI Express 4 Port SATA RAID Controller
- ARC-1220 PCI Express 8 Port SATA RAID Controller
- ARC-1230 PCI Express 12 Port SATA RAID Controller
- ARC-1230ML PCI Express 12 Port SATA RAID Controller
- ARC-1231ML PCI Express 12 Port SATA RAID Controller
- ARC-1260 PCI Express 16 Port SATA RAID Controller
- ARC-1260ML PCI Express 16 Port SATA RAID Controller
- ARC-1261ML PCI Express 16 Port SATA RAID Controller
- ARC-1280 PCI Express 24 Port SATA RAID Controller
- ARC-1280ML PCI Express 24 Port SATA RAID Controller
- ARC-1680 PCI Express 8 Port SAS RAID Controller
- ARC-1680LP PCI Express 8 Port SAS RAID Controller
- ARC-1680i PCI Express 8 Port SAS RAID Controller
- ARC-1680x PCI Express 8 Port SAS RAID Controller
- ARC-1681 PCI-X 8 Port SAS RAID Controller
These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using either SAS or SATA II drives.
arcmsr supports management and monitoring of the controller through the bioctl(8) and envstat(8) commands.
Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or
RAID volumes will require to have the password disabled in the firmware; otherwise a Permission denied error will be reported by bioctl(8).
When a RAID 1 or 1+0 volume is created, either through the bioctl(8) command or controller's firmware, the volume won't be accessible until
the initialization is done. A way to get access to the sd(4) device that corresponds to that volume without rebooting, is to issue the fol-
lowing command (once the initialization is finished):
$ scsictl scsibus0 scan any any
The arcmsr driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the
bioctl(8) command.
EVENTS
The arcmsr driver is able to send events to powerd(8) if a volume or any drive connected to the volume is not online. The state-changed
event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens.

The arcmsr driver first appeared in NetBSD 5.0.
