Securing VIO Server
======================================================
To use ssh, comes pre-installed with vio 1.3 onwards,
$ oem_setup_env
# ln -s /usr/bin/ssh /usr/ios/oem/ssh
# ln -s /usr/bin/scp /usr/ios/oem/scp
# exit
$
Stopping Telnet & Ftp
$ stopnetsvc telnet
$ stopnetsvc ftp
Blocking any unused network sockets
The VIOS comes with a predefined set of rules, defined in /home/ios/security/viosecure.ctl.
The IP filters are activated by issuing a
$ viosecure -firewall on -reload
and they can be listed with the command
$ viosecure -firewall view

=======================================================================================
If /home/ios/security/viosecure.ctl is missing (due to whatever reason),
you can still activate IP filters by issuing
$ viosecure -firewall on -force -reload
To block any traffic to port 80, 20 and 21, apply the following commands as padmin:
$ viosecure -firewall deny -port 80
$ viosecure -firewall deny -port 20
$ viosecure -firewall deny -port 21
and check your results with another "view" command.
$ viosecure -firewall allow -port 20 -remote

Save Upgrade Data
The Save Upgrade Data task is used to save the current HMC configuration in the special disk partition on the HMC.
This task is used before you migrate the current HMC software level to the new version
Note: The special disk partition can hold only one generation of backup data. Every time you perform this task,
previous backup will be overwritten by the latest backup.

http://publib.boulder.ibm.com/infocenter/eserver/v1r2s/en_US/index.htm?info/iphau/loccodes.htm - Understanding Location Codes
Q:Having a few problems understanding the mapping between physical location codes, HMC location codes, and AIX (virtual?)
location codes. Mainly this is a problem with I/O devices (no micropartitioning). Does anyone know a good doc/redbook
that goes through this?
A:the p520/5520 hardware guides cover this, as does the infocenter on the HMC Anyone have a link to the hardware guide?
I keep getting stuck in the 'Hardware Information Center' and can't find AIX location codes in there. For instance the
AIX install tells me hdisk0 is at 08-08-00-3,0. How do I map that location to the HMC Uxxxx.ccc.sssssss,Bus 2,Slot C4
(or wherever) location code?

1. Run IOS commands as root
According to IBM you should never work as root on VIO servers. However, if you login as user padmin and type
oem_setup_env
you get the root credentials (without even been asked for a password).
By default the ioscli commands are not available for the root user. All ioscli commands are in fact calls of /usr/ios/cli/ioscli with the command as argument. You see this if you list the aliases of the padmin user.
Knowing this you can use all ioscli commands as user root by appending /usr/ios/cli/ioscli. Instead of »lsmap -all« you would type
root@vios# /usr/ios/cli/ioscli lsmap -all
If you set an alias
alias i=/usr/ios/cli/ioscli
you could even type
root@vios# i lsmap -all
IOS - Information and Maintenance1. List all ioscli commands
$ help
You can type
$ help <command>
to display a command's syntax, e.g
$ help lsmap
Usage: lsmap {-vadapter ServerVirtualAdapter | -plc PhysicalLocationCode |
-all} [-type BackingDeviceType ... | -net]
[-field FieldName ...] [-fmt delimiter]
Displays the mapping between physical and virtual devices.
-all Displays mapping for all the server virtual adapter
devices.
-vadapter Specifies the server virtual adapter device
by device name.
-plc Specifies the server virtual adapter device
by physical location code.
-type Specifies to display virtual devices whose backing
device matches the type given.
-net Specifies supplied device is a virtual server
Ethernet adapter.
-field Specifies a list of fields to be displayed.
-fmt Divides output by a user-specified delimiter.

3. Create a Virtual SCSI Host Adapter
This has to done on the HMC for the profile of the VIO server: You create a new Virtual SCSI Host-Adapter and assign it
only to your client LPAR.
The same slot ID should then be assigned to a new client adapter in the client LPAR's profile.
You can do these steps dynamically to avoid a restart of the VIO server. Use the Dynamic Logical Partitioning option
for that. If you go for the dynamic option don't forget to do the same assignments in the profiles aswell, otherwise
your LPAR loses all storage after a new start of the VIOS!
After dynamically adding the server hostadapters you have to rerun the configuration mamager before you can see the
new vhost device:
$ cfgdev
4. Remove a Virtual SCSI Host Adapter
$ rmdev -dev vhostX [ -recursive ]
The option »-recursive« can be used to remove all still attached child devices.
Then remove the adapters dynamically from the VIO server aswell as from the VIOS' profile.
5. Assign a Disk/LV to a Virtual SCSI Host Adapter
To map hdisk22 to vhost1 just type
$ mkvdev -vdev hdisk22 -vadapter vhost1
vtscsi19 available
The VIO server assigns the next free number (19 here) and creates the mapping device vtscsi19. But you can specify your own name for the mapping device by making use of the »-dev« option:
$ mkvdev -vdev hdisk22 -dev vthdisk22_barney -vadapter vhost1
vthdisk22_barney available
If you use LVs rather than whole disks or LUNs the same rules apply:
# default mapping device
$ mkvdev -vdev lpar21_lv03 -vadapter vhost1
vtscsi19 available
# custom mapping device
$ mkvdev -vdev lpar21_lv03 -dev vtdisk21_lv03 -vadapter vhost1
vtdisk21_lv03 available
6. Unassign a Disk/LV from a Virtual SCSI Host Adapter
$ rmvdev -vtd vtscsiXX

2. Create a Shared Ethernet Adapter
To create a Shared Ethernet Adapter (SEA) you need:
a physical adapter as backend: <PHYS>
a virtual adapter as defined in the VIOS' profile: <VIRT>
an internal VLAN ID: <VLAN>
If you use the Shared Ethernet Adapter Failover capability of recent IOS releases you also need
a second virtual adapter as defined in the VIOS' profile: <CONT>
for the control channel:
# simple:

Some New Virtual Disk Techniques
The AIX Virtual User Group (Central Region, U.S.) recently hosted an informative webinar presented by Janel Barfield. Download the presentation or listen to a replay. The topics covered in the presentation and replay go nicely with some AIXchange blog entries (here and here) I previously wrote.
By listening to the webinar, I learned a few other techniques that we can all benefit from. For instance, in my VIO server, I tried creating a file-backed virtual disk (obviously on this test box I was using rootvg; if this were a production machine I'd create another volume group and use that instead):
mksp -fb fbpool -sp rootvg -size 1G
This added a new file system to my rootvg:
lsvg –lv rootvg
fbpool jfs2 4 4 1 open/syncd
/var/vio/storagepools/fbpool
In my environment I did an lsmap –all | more and found a client to try this with. I ran:
mkbdsp -sp fbpool 500m -bd test_disk -vadapter vhost2
Here's the output I saw:
Creating file "test_disk" in storage pool "fbpool".
Assigning file "test_disk" as a backing device.
vtscsi5 Available
test_disk
I wanted to see what would appear in the file system that I just created, so I ran:
ls -la /var/vio/storagepools/fbpool
total 1024008
drwxr-xr-x 3 root system 256 Nov 03 15:24 .
drwxr-xr-x 3 root staff 256 Nov 03 15:18 ..
-rw-r--r-- 1 root staff 206 Nov 03 15:24 .test_disk
drwxr-xr-x 2 root system 256 Nov 03 15:18 lost+found
-rw-r--r-- 1 root staff 524288000 Nov 03 15:24 test_disk
Interestingly, that .test_disk file contains some XML data describing the disk that I just created:
more /var/vio/storagepools/fbpool/.test_disk
<?xml version="1.0" encoding="UTF-8"?>
<device vios_version="1.0" name="/var/vio/storagepools/fbpool/test_disk" id="000
0bb8a0000d40000000117b276f9d8.1700000004" imagetype="SP_LOCAL" refcount="1">
</device>
When I look at the mapping that exists after creating the disk, I can see:
lsmap -vadapter vhost2
SVSA Physloc Client Partition ID
--------------- -------------------------------------------- ------------------
vhost2 U7998.61X.100BB8A-V1-C15 0x00000007
VTD vtscsi2
Status Available
LUN 0x8100000000000000
Backing device hdisk3
Physloc
U78A5.001.WIH0A68-P1-C6-T1-W5005076801303022-LD000000000000
VTD vtscsi5
Status Available
LUN 0x8200000000000000
Backing device /var/vio/storagepools/fbpool/test_disk
Physloc
U78A5.001.WIH0A68-P1-C6-T1-W5005076801303022-LD000000000000
This shows me that now I have the new virtual disk with the backing device being handled by the newly created file. When I run cfgmgr in my partition that uses vhost2, I see a new disk. AIX running in my partition doesn't differentiate between the file-backed storage or my normal hdisk-backed storage (hdisk1 is my newly created disk in this instance).
# lspv
hdisk0 00004daa45ffe3fd rootvg active
hdisk1 none None
# lsdev -Cc disk
hdisk0 Available Virtual SCSI Disk Drive
hdisk1 Available Virtual SCSI Disk Drive
I can now use this disk as I would any other on my machine.
On the topic of virtual optical disks, one point brought up in the webinar was that instead of running multiple unloadopt/loadopt commands when using virtual optical disks, you can just use loadopt –f to force the disk image to load, even if a disk image is already loaded. This makes it simpler when using more than one CD to load the OS for instance, as you don't have to unloadopt before running the loadopt –f command when switching between disk images.
