The driver will output messages indicating which devices have been added or removed and the controller, bus, target and lun used to address each device. Hello, What you are seeing here are two partitions both on the first controller and the first disk. The normal protocol is a four-step process: You need to be aware of this to be able to accurately predict what device nodes will be matched with what logical volumes. Initially you will get the following: Have you figured out how to associate c0dx with VolGroupXX?

If normal disk is taken the output is as follows: Note moynt that if no sequential access devices or medium changers are detected, the SCSI core will not be engaged by the action of the above script. You must be knowing what this directory is for.
The “dump” command or other backup utility software could be misled, potentially ruining backups. Now we have this ignoring controller 1.
The “hole” between 1 and 3 will close up. If people are going to be storing important information on that device you had better have good backups.

Just type the model or part number you are looking to upgrade in the search box as shown Click to enlarge. SCSI error handling for tape drives and medium changers The Linux SCSI midlayer provides an error-handling protocol that is initiated whenever a SCSI command fails to complete within a certain amount of time which can vary depending on the command.
Guess maybe I should have provided a link to info about Linux management tools for the HP smartarray I can’t see it on my VZ control panel Proxmox Thanks. Note also that most tape drives will not oblige in aborting commands, and sometimes it appears they will not even obey a reset command, though in most circumstances they will.

moynt Are you new to LinuxQuestions. 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.
You will have to create “Physical Volume s ” like c0dxp1 and so on as shown in diagram over that c0dx.
However, even with the ability to predict the mapping, there is still the potential for problems with online reconfiguration. Additionally, note that the driver will not engage the SCSI core at init time. The time ciss is Visit the following links: The last two lines must be changed to use “c0d2p1” and “c0d3p1” instead of “c0d3p1” and “c0d4p1”. The device naming scheme is:.

In this case, the collection of logical volumes on the two storage boxes will appear to to the OS to be directly attached to the one SmartArray installed in the server, like so: Anonymous June 27, at Join our community today! Edited 4 Years Ago by Casperjames.
In essence, it will fill in the first hole left by deleting a logical volume. Those cciss devices don’t appear in mount command output. 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.
The linux device nodes associated with those devices would be: It is likewise possible to reconfigure a Compaq SmartArray controller to dynamically add and remove logical volumes without the need for a reboot.
