![]() ![]() You can also use VxVM to dynamically configure storage while the system is active. VxVM provides the tools to improve performance and ensure data availability and integrity. If the root disk (or another disk) was involved with the reinstallation, any volumes or mirrors on that disk (or other disks no longer attached to the system) are now inaccessible. To install SFHA on two nodes simultaneously ,we should configure the password less authentication configured on both Solaris host. If you want to install veritas cluster server along with veritas volume manager,choose SFHA. It gives you the ability to add and remove mirrors, work with RAID arrays. The simple installer will help you what product you want to install on the servers. This allows volumes to span multiple disks and LUNs. Veritas Disk Check The Veritas Volume Manager is a package that allows you to. VxVM vxsparecheck NOTICE V-5-2-191 Failures have been detected by the VERITAS Volume Manager: failed disks: adg01 failed plexes: vol1-01 vol2-01 failed. VxVM overcomes restrictions imposed by hardware disk devices and by LUNs by providing a logical volume management layer. Additionally, VxVM provides features that enhance fault tolerance and fast recovery from disk failure or storage array failure. By supporting the Redundant Array of Independent Disks (RAID) model, VxVM can be configured to protect against disk and hardware failure, and to increase I/O throughput. you also have the option of mirroring your root drive with it. The new disk (c1t4d0) will automatically be named disk02 under VxVM. We would have to choose an alternate disk for the replacement of the failed disk. VxVM provides easy-to-use online disk storage management for computing environments and Storage Area Network (SAN) environments. Veritas Volume Manager encapsulated root disk If you have purchased the Veritas Volume. Select an operation to perform: 5 List the failed disks under VxVM using list option, and select the failed disk disk02 from disk group mydg. A VxVM volume appears to applications and the operating system as a physical device on which file systems, databases and other managed data objects can be configured. 2) When the disk has been removed, select option 5 - Replace a failed or. Once this option has been picked, follow the prompts to remove the disk. and select option 4 - Remove a disk for replacement. 1) First remove the disk using the vxdiskadm options list. * HP-UX 11i v2 - VxVM 5.Veritas TM Volume Manager (VxVM) by Symantec is a storage management subsystem that allows you to manage physical disks and logical unit numbers (LUNs) as logical devices called volumes. After the failure has been determined to be a permanent failure perform below steps. * HP ServiceGuard for HP-UX - VxVM 5.0.1: Problem with Importing Cloned LUN on the Same Host. * Veritas Volume Manager 5.0 for HP-UX Software - Handling Disks with Duplicated Identifiers in Veritas Volume Manager (VxVM) 5.0. # vxdisk updateudid disk4 disk5 disk6 disk7 # vxdisk clearimport disk4 dik5 disk6 disk7 Several disk may incorrectly report do have duplicate udids. Under this task, removing 5.01 and installing 5.0 can change the state of the DDL database. There is a uncommon situation where this can occur, when VxVM 5.01 is rollback to the previous 5.0 version. When this situation occurs, volumes groups can be imported tagging those disk a clone devices, or updating the udid values. This feature tries to prevent the situation where two or more disk contains the same private area, and VxVM may use the first available disk or other undefine behaviors. This is a common situation using SAN based tools to clone LUNs. This is most notable when running a vxdisk list command. On Veritas Volume Manager 5.x, the Unique Disk Identifier (udid) has been introduced to handle the situation where two or more disks has their private areas duplicated. Failure to follow this procedure could result in a duplicate entry for the replaced disk in VxVM. How to correct udid mismatch on vxdisk list command output If you use Veritas Volume Manager, you ideally use it only for shared. ![]() Change / update the clear udid on the disk. You can achieve a root disk layout where slice 7 is 32 megabytes in size, and use. Clear the locks on the disk, using device name:Ĥ. IF that does not correct the problem, the following procedure can be use to clean the state.ģ. In most cases, just deporting the disk group and using vxdisk updateudid command to sync the DDL with the disk private area will correct the problem.
