VxVM tutorials : Root disk Encapsulation and Mirroring
VxVM Tutorials Installing VxvM in VMware virtual machine Creating Basic volume and file system Volume layouts and layered volumes Comparing layered and non-layered Volumes Volume resize with vxassist and vxresize Replacing a failed disk under VxVM One of the best feature of VxVM or any volume manager for that matter is redundancy of data. Root disk is one of the most important disk as it contains the complete OS. So it is very important to mirror the root … [Read more...] about VxVM tutorials : Root disk Encapsulation and Mirroring
VxVM tutorials : Comparing layered and non-layered volumes
VxVM Tutorials Installing VxvM in VMware virtual machine Creating Basic volume and file system Volume layouts and layered volumes Root disk Encapsulation and Mirroring Volume resize with vxassist and vxresize Replacing a failed disk under VxVM You must have thought that, when we can create a simple RAID 1+0 or RAID 0+1 volume, why we go for layered volumes with complicated structure and sub volumes?! The answer is simple. The main reason behind using … [Read more...] about VxVM tutorials : Comparing layered and non-layered volumes

How to create an I/O domain
An I/O domain has a direct access to the underlying hardware devices. It is used generally in a case where you want performance improvements avoiding the overheads to access the hardware indirectly through control domain. You can create I/O domain is 2 ways: 1. Using the entire PCIe BUS 2. Using a PCIe end point device Creating I/O domains using PCIe buses Now as shown in ther digram we can assign a complete PCI bus(pci_1) to the I/O domain assuming there are no disk or network devices on … [Read more...] about How to create an I/O domain
How to save LDOM configuration and restore from xml file
It is necessary to save LDOM configuration to rebuild it in future in case of a hardware failure on the physical server. Now every LDOM has constraints defined which can be saved as xml file. This file will contain all the resource allocation to a LDOM. Saving LDOM configuration To save constraints of a single domain : # ldm list-constraints -x ldom_name > ldom_name.xml To save constraints of all the domains : # ldm list-constraints -x > all_ldoms.xml Restoring LDOM configuration There … [Read more...] about How to save LDOM configuration and restore from xml file
How to reset LDOM configuration to factory default
The factory-default configuration is the configuration when you first time install the Oracle VM Server for SPARC software on to a fresh Solaris OS. To set the physical server to factory-default configuration : 1. Remove all the guest LDOMs 2. Remove all the saved LDOM configurations 3. Restore the factory default configuration a. from command line b. from service processor Stop all the ldoms, unbind and delete them First step is to stop all the domains, unbind them and remove … [Read more...] about How to reset LDOM configuration to factory default
ZFS Tutorials : Creating ZFS snapshot and clones
ZFS snapshots zfs snapshot is a read-only copy of zfs file system or volume. They consume no extra space in the zfs pool and can be created instantly. They can be used to save a state of file system at particular point of time and can later be rolled back to exactly same state. You can also extract some of the files from the snapshot if required and not doing a complete roll back. Let us take a look at the steps involved in creating a snapshot of zfs file system. Creating and destroying … [Read more...] about ZFS Tutorials : Creating ZFS snapshot and clones
