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.

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 to remove it from the odm and run cfgmgr again. Unmap Disk Vio Server Then I removed the disk from the volume group and the AIX Object Data Manager (ODM), with the rmdev command. # ps –ef | grep sync # lsvg –l rootvg |

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.

Figure 4.

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 -
