rmdev all the devices & run cfgmgr .. What will do is test it without them if problem still occur will reinstall them or install another version, and just test it, will let you know. Remove deleted adapter from client (from profil too) 6. I also ensure that we update the VIOS and LPAR partition profile (on the HMC) with these newly created virtual adapters. http://mixtecadigital.com/to-remove/unable-to-remove-tire.html
All other LPARs will not see the adapter or the tape drives. Jaco Bezuidenhout replied Aug 5, 2011 If you have VIOS managing the LPAR (possibly virtual Server , since the new name change when running SDMC and not HMC), then make sure First I needed to identify the DS8300 disks which would be used for the data migration. However, for the application/data volume groups, we chose to use the migratepv command.
Then, I used the mirrorvg command to create an exact copy of the data on the new disk. With the storage carved up, we were able to assign the new LUNs to the existing AIX hosts and perform the migration. you will get tape with the status "available" Regards Aseem A S Top Best Answer 0 Mark this reply as the best answer?(Choose carefully, this can't be changed) Yes | No step 2: $ mkvdev -vdev rmt0 -vadapter vhost0 vttape0 Available To list all virtual target tape devices step 3: $ lsdev -type tape -virtual vttape0 Available Virtual Target Device - Tape
If you need higher queue depths for the devices, the number of LUNs per adapter is reduced. This disk has been allocated to an existing volume group (rootvg). yawe_frek replied Aug 5, 2011 Try using the rmdev -dl
Chan. 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 Lee.. Go to the other LPAR and run 'cfgmgr' and it will be in the "Defined" state.
Review the Resources section below to find out more. Rmdev Hdisk ON CLIENT: # errpt <--error report will show "PATh HAS FAILED" IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION DE3B8540 0324120813 P If it helps (and it usually does), draw pictures to help demonstrate answers to these questions. Let’s review the current state (the state of the environment prior to migrating to the new storage).
NPIV adds another dimension to storage virtualization on the Power platform. And that’s just one of the many advantages to using this wonderful device. How To Remove Vhost In Vio I recommend this approach and my examples will cover how I chose to deploy this type of configuration. Rmvdev Will let you know Monday.
You can refer to Figure 10. this contact form The truth is right now I don't know, as about a year ago I had huge struggles on virtualizing tape drives. Once this was completed, we worked with the storage team to determine what type and how many LUNs we would require for each of the AIX systems that were migrating to 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.

Is there a way we can check the physical location code of the failing disk? Rmvdev Vhost E.G., if we want to use a queue_depth of 25, that allows 510/28= 18 LUNs. The mirrorvg command would be used to migrate the operating system (rootvg) from the old ESS to the DS8300.
This includes performing a mksysb and savevg backup, followed by a file level backup with our corporate backup tool. Any other LPAR doing a cfgmgr will pick up the drives, but will show them as "Defined". -or- The other way of virtualizing (probably what you don't have): The assignment of Solid State And Hybrid Drives Improve Performance Backup Reliability Factors Part 2 Companies Vision Solutions Toolbox for IT My Home Topics People Companies Jobs White Paper Library Collaboration Tools Discussion Groups Mkvdev Command For example, our design document stated the following: Ensure that the following software is installed on all AIX systems, at these levels: AIX 5200-05 IY62165 Abstract: Target device rejects writes -
On the client LPAR, we ran cfgmgr to discover the new hdisk. Ad. Watson Product Search Search None of the above, continue with my search Configuring Virtual Tape on Virtual I/O Server Technote (troubleshooting) Problem(Abstract) Step by Step Virtual Tape Drive Configuration Environment Virtual Check This Out To ensure that the boot disk and boot list had been configured correctly, I would reboot the system to verify.
There were two LVM utilities at the core of our data migration strategy (mirrorvg and migratepv). With Atape you might get the tape drive properly named as "IBM 3450 LTO Ultrium Tape Drive".
