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
Code:
[root@zzz] / > lsdev -Cc adapter | grep fcs
fcs0 Available 00-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs1 Available 00-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs2 Available 01-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs3 Available 01-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs4 Available 05-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs5 Available 05-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
Can we say the "physical" FC adapter here are actually the real physical FC adapter from Power Machine which are assigned to the lpar not via VIOS (with virtual FC adapter) ?
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)

DESCRIPTION
Note: this tunable is obsoleted and has been renamed to beginning with release HP-UX 11i v3.
This tunable notifies the tape driver whether it should allow access to device special files without the no-rewind-on-close option. When
this tunable is on the tape driver will fail any open on a tape device special file without the no-rewind-on-close option (that is, or with
a status of
The tunable allows the safe sharing of tape devices in SAN tape backup solution configurations. The disabling of device special files
without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command on close from
HP-UX systems via standard tape commands like which would corrupt a backup in process.
Who Is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately.
When Should the Tunable Be Turned On?
This tunable should be turned on if the system is going to be used in a SAN tape backup solution configuration.
What Are the Side Effects of Turning the Tunable On?
The tape driver will fail any open to a tape device special file that does not have the no-rewind-on-close option with a status of This
behavior prevents the usage of any tape device special file without the no-rewind-on-close option.
When Should the Tunable Be Turned Off?
This tunable should be turned off if the system is not part of a SAN tape backup solution configuration or the system utilizes will not
function unless it has access to device special files without the no-rewind-on-close option.
What Are the Side Effects of Turning the Tunable Off?
A rewind may be issued from this system accidentally on close possibly corrupting a backup being issued from another system on the SAN.
What Other Tunables Should Be Changed at the Same Time?
None.
