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)

smp_ena_dis_zoning
SMP_ENA_DIS_ZONING(8) SMP_UTILS SMP_ENA_DIS_ZONING(8)NAME
smp_ena_dis_zoning - invoke ENABLE DISABLE ZONING SMP function
SYNOPSIS
smp_ena_dis_zoning [--disable] [--ena-dis=ED] [--expected=EX] [--help] [--hex] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--save=SAV]
[--verbose] [--version] SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Management Protocol (SMP) ENABLE DISABLE ZONING function request to a SMP target. The SMP target is identified by the
SMP_DEVICE and the --sa=SAS_ADDR. Depending on the interface, the SAS_ADDR may be deduced from the SMP_DEVICE. The mpt interface uses
SMP_DEVICE to identify a HBA (an SMP initiator) and needs the additional ,N to differentiate between HBAs if there are multiple present.
If neither --disable nor --ena-dis=ED options are given then enable zoning (i.e. "--ena-dis=1") is assumed.
This function does not change the state of the current zoning enabled flag (as seen in the REPORT GENERAL response). Such a state change
will occur on a subsequent invocation of the ZONE ACTIVATE function.
OPTIONS
Mandatory arguments to long options are mandatory for short options as well.
-d, --disable
set the 'enable disable zoning' field in the SMP request to 2 which will disable zoning.
-e, --ena-dis=ED
set the 'enable disable zoning' field in the SMP request. ED may take these values: 0 for no change, 1 for enable zoning (default)
and 2 for disable zoning. If this option and the --disable option are both given then they cannot contradict one another.
-E, --expected=EX
set the 'expected expander change count' field in the SMP request. The value EX is from 0 to 65535 inclusive with 0 being the
default value. When EX is greater than zero then if the value doesn't match the expander change count of the SMP target (i.e. the
expander) when the request arrives then the target ignores the request and sets a function result of "invalid expander change count"
in the response.
-h, --help
output the usage message then exit.
-H, --hex
output the response (less the CRC field) in hexadecimal.
-I, --interface=PARAMS
interface specific parameters. In this case "interface" refers to the path through the operating system to the SMP initiator. See
the smp_utils man page for more information.
-r, --raw
send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr.
-s, --sa=SAS_ADDR
specifies the SAS address of the SMP target device. The mpt interface needs this option and it will typically be an expander's SAS
address. The SAS_ADDR is in decimal but most SAS addresses are shown in hexadecimal. To give a number in hexadecimal either prefix
it with '0x' or put a trailing 'h' on it.
-S, --save=SAV
set the 'save' field in the SMP request. SAV may take these values: 0 for updating the shadow values (default), 1 for updating the
saved values, 2 for updating shadow values and if available the saved values, 3 for updating both saved and shadow values.
-v, --verbose
increase the verbosity of the output. Can be used multiple times.
-V, --version
print the version string and then exit.
CONFORMING TO
The SMP ENABLE DISABLE ZONING function was introduced in SAS-2 .
