If you are, then I recommend you review the latest IBM Redbook on migrating from physical to virtual storage (see Resources). like: cd0 Available SATA DVD-RAM Drive) 2. I came to know through few colleagues it will hung the server. First, we identify the NetApp LUNs which will be used for the data volume group migration. Check This Out
Tape drives are in a defined state Lebang Makapan asked Aug 5, 2011 | Replies (25) Hi all, I'm very new in the AIX storage, we just migrated from P5 to We verify that the new disk and paths are available. Then you go to VIOS and assign it to another LPAR and you go to that LPAR and run cfgmgr and the drives will show Defined.

For example, if you are migrating (VIOS presented disk) from IBM DS to NetApp storage, then it is likely that you will need to consider provisioning new VIO servers for the Most vendors provide tools to help with the planning and verification, for example, IBM provides the Fix Level Recommendation Tools website, as well the IBM HBA support site (see the Resources Please try the request again.
Start with a diagram that encapsulates your current state, then another that describes how the new device will fit, followed by the proposed migration process or processes.

Take the time to design how your new SAN storage device is going to fit into your existing SAN.

It can migrate storage transparently, from one storage device to another, without the host system ever being aware of the move. First, we add the new disk (hdisk11) to rootvg.
Each host had at least two FC adapters connected to our SAN. Rmdev Hdisk ReplyDeleteRepliesaixJuly 24, 2013 at 12:34 PMHi, yes it is possible. The following diagram shows the high-level view of the SAN storage and AIX LPAR connectivity to the existing SAN Fabric: Figure 1. The Virtual I/O Server owns the physical resources and acts as server or, in SCSI terms, target device.
At this point, we have reached our desired end state. cfgmgr (on other client lpar) <--bring up cd0 device on other client (Because VIO server adapter is configured with "Any client partition can connect" option, these pairs are not How To Remove Vhost In Vio Jaco Bezuidenhout replied Aug 12, 2011 Hi again Leeee, My curiosity got me to free up 10 minutes to dig into my documentation and into IBMs labyrinth, Maybe you can spot Rmvdev Our planning also captured each LPAR's hostname, the existing AIX hdisk names, the existing SDD (vpath) configuration, the World Wide Port Name (WWPN) for each FC adapter, the current FC adapter
You should start with few things already suggested here . http://webjak.net/to-remove/surgery-to-remove-mirena.html PVID is mainly needed for LVM, but here you don't have any VGs or LVs on the disk.

Both VIOS will SAN boot from NetApp storage. Vio Vscsi Mapping
Create new adapter on client (in profil too) <--cfgmgr on client 8. aseem as replied Aug 12, 2011 Hi, You can just delete all the tape rmt0,rmt1....rmt19 through the command "rmdev -Rdl rmto" and after completion just run "cfgmgr". Ad. http://webjak.net/to-remove/remove-incredibar.html Without Atape on VIOS you will get a method error when doing a cfgmgr - this should be viewed as normal, since you can't virtualize or use smc0.
Review the vendor's storage support matrix. Rmvdev Vhost ON VIOS2: # lsmap -all <--checking disk mapping on VIOS2 VTD testdisk Status Available LUN 0x8200000000000000 Backing device hdiskpower1 on VIO server: [email protected]: / # lsdev -Cc adapter vhost0 Available Virtual SCSI Server Adapter vhost1 Available Virtual SCSI Server Adapter vhost2 Available Virtual SCSI Server Adapter The client partition accesses
The VIOS pair (hvio1 and hvio2) are serving the DS8300 LUNs as virtual SCSI (VSCSI) disk to the client LPAR. This new hdisk has been included in the existing root volume group (rootvg, also shown in Figure 8). Toolbox.com is not affiliated with or endorsed by any company listed at this site. Mkvdev Command Also, one should set the queue_depth attribute on the VIOC's hdisk to match that of the mapped hdisk's queue_depth on the VIOS.
Hence we will not load any "cvscsi" function for AIX 6.1 servers( please refer the link mentioned above in this post). 0> cvscsiBelow will be the o/p: read vscsi_scsi_ptrs OK, ptr I NEVER try to remember - that is cognitive learning and it hurts. The system returned: (22) Invalid argument The remote host or network may be down. navigate here And that’s just one of the many advantages to using this wonderful device.
Having the ability to move data between source and targets disks, while the system/applications are still running, is a huge benefit in an operational computing environment. See the Resources section for more information on the IBM SVC. Lebang Makapan replied Aug 12, 2011 Which ones are required,like I explained to jaco,on 3 alpas that use VIO al have different versions of Atape drivers,and 2 tape drives are fine,but disks have its own adaper, same as tapes.
mkvdev -vdev cd0 -vadapter vhost0 <--it will create vtoptX as a virtual target device (check with lsmap -all ) 4. I recommend this approach and my examples will cover how I chose to deploy this type of configuration. This publication guides you through the migration process and offers several methods for migrating. Romeo Ninov replied Aug 5, 2011 So, you have drivers for tape drives in the kernel and no tape device in to the system Top Best Answer 0 Mark this reply
If Atape is installed on VIOs, then VIOs will identify the drive with the correct naming, but when you try to firtualize and assign the drive to an LPAR (i.e. 'mkvdev I’m going to assume that you or your SAN storage administrator have already cabled, configured and connected your new SAN storage device to your existing SAN. Obviously before we could start, our storage team had to first attach and configure the new DS8300 into our existing SAN. Eth.
Next, we run the rmvdev command to remove any virtual target device (VTD) mapping associated with the hdisk (e.g. VSCSI VSCSI - Stor. Lebang Makapan replied Aug 10, 2011 Hi Jaco, Yes we are using the VIO on the switch side, not Alpa, with one physical port can see 8 virtual port, we used
