List physical drives on controller in slot 0: It is likewise possible to reconfigure a Compaq SmartArray controller to dynamically add and remove logical volumes without the need for a reboot. This is because at driver init time, the SCSI core may not yet be initialized because the driver is a block driver and attempting to register it with the SCSI core in such a case would cause a hang. Files Device nodes The device naming scheme is as follows: The show tech command in H3C is display diagnostic-information. This book contains many real life examples derived from the author’s experience as a Linux system and network administrator, trainer and consultant.

Linux – Hardware This forum is for Hardware issues.
Have something to contribute to this discussion? SCSI tape drive and medium changer support SCSI sequential access devices and medium changer devices are supported and appropriate device nodes are automatically created e. Device c0d0p1 is controller 0 disk 0 partition 1 and if you created logical drives with the raid controller you should be seeing a device c0d1 and will need to create mounf on it.
It can do both reporting and management. They hope these examples will help you to get a better understanding of the Linux system and that ccis feel encouraged to try out things on your own. You are currently viewing LQ as a guest. Please visit this page to clear all LQ-related cookies. The driver then notifies the SCSI midlayer of these changes.

Disk information when RAID is enabled. You need to be aware of this to be able to accurately predict what device nodes will be matched with what logical volumes. Here is a link to a quick film about raid: As is the case with adding and removing SCSI disks, there are some pitfalls to avoid when adding and removing logical volumes with a Compaq SmartArray controller. Ciss c0dx ccisss like a normal DISK.
Disk information when RAID is enabled.
Vciss the command cannot be aborted and the device cannot be reset, the device will be set offline. You must be knowing what this directory is for. Things are getting better, and for example it is now possible with Linux to dynamically add and remove SCSI disks to the system without rebooting. Having trouble installing a piece of hardware?
The only disk devices that are presented to the kernel monut logical drives that the array controller constructs from regions on the physical drives. The normal protocol is a four-step process: If you need to reset your password, click here.
List physical drives on controller in slot 0: The device naming scheme is:. I am working on: This document will explain how Linux arrives at the mapping between device nodes and logical volumes, so that you may anticipate what other changes will be required after reconfiguring your array controller.
Adil Mhaisker June 16, at 9: In essence, it will fill in the first hole left by deleting a logical volume. If you already have c0dx created, you should be able to see it in the output of command “fdisk -l”.
Unfortunately, there was no direct and simple answer from the great Google. C0dx will NOT appear in mount command. It is likewise possible to reconfigure a Compaq SmartArray controller to dynamically add and remove logical volumes without the need for a reboot. Introduction to Linux – A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each ccoss.
Have you figured out how to associate c0dx with VolGroupXX?

So if you had two array controllers each with 5 logical volumes, they would be two sets of logical volumes, each numbered 0, 1, 2, 3, 4. It is important for the driver to prevent the kernel from accessing the physical drives directly, since these drives are used by the array controller to construct the logical drives. Look at this post, for info on how to mout the drives in the array.
