SVM

Brief About SVM

The Solaris volume manager (SVM) is a free component of  Solaris 9 and Solaris 10. It was previously known as Solstice DiskSuite. SVM software provides mechanisms to configure physical slices of harddrive into logical volumes. As such it introduces additional level of complexity and should not be used unless absolutely necessary. On Solaris 10 using ZFS is a better alternative. ……

SVM Disk Replacement

we are basically covering the procedure to replace a failed disk under SVM in solaris. …

Increasing file system SVM-Concatination

UNIX file systems (UFS) can be expanded this way. The concatenation is good only for small random I/O and for even I/O distribution. On the other hand, striping is advantageous for large sequential I/O and for uneven I/O distribution, because striping will increase performance by accessing data in parallel….

SVM Root Disk Replacement

Replacing failed disk in ZFS. Now let us see some of the examples of replacing failed root disk under Solaris volume manager. Note that the failed root disk is under a mirrored configuration….

Converting SVM to VxVm

Converting a Solaris volume manager metadevice to VxVM, after executing /opt/VRTSvxvm/vmcvt/bin/doconvert and rebooting the conversion does not complete upon reboot. This is due to /etc/lvm/md.cf file is not cleared of all meta devices and VxVM detects meta data devices by reading this file…..

MetaDB Corruptions / Resolution

If the state database replica quorum is not met, for example, due to a drive failure, the system cannot be rebooted into multiuser mode. This situation could follow a panic (when Solaris Volume Manager discovers that fewer than half the state database replicas are available) or could occur if the system is rebooted with exactly half or fewer functional state database replicas. In Solaris Volume Manager terms, the state database has gone “stale.” This task explains how to recover from this problem…..
