Problem presenting disks EVA3000 - Proliant DL380 - QLA2312 - Linux Debian - Kernel 2.4

[Miquel_2]

Hi all,

We have a problem with some disks created in HP StorageWorks EVA3000 presented to a linux system on a Proliant DL380 G4 with QLA2312 HBA. We created and presented 3 disks at luns 1,2 and 3, and the system view all disks and their capacities using lshw from system prompt, but when the tries to access the disks on luns 1 and 3 then the error "device not ready" is returned.

Have anybody some idea about this ?
Thank you.


This is the lshw output:

[Uwe Zessin · Accepted solution]

It sounds like you have a single-path configuration without a multipath driver.

'not ready' means that the virtual disk is maintained by the other controller. The controller you are currently connected to presents the disk so that a multipath drives becomes aware of any standby data paths.

You can send a SCSI 'start unit' command to the LUNs and they will fail over. Other way is to use the preferred path setting on the virtual disk properties page - use Controller-A/B failover with failback.

Also, go over the host entries and make sure that the Operating System type is set to '(SUN) Solaris'.

We used Path B failover/failback and all its ok, we can now make filesystem in luns 1 and 3.

Thank you !!

[Miquel_2]

Specify Controller B failover/failback makes accesible all disk devices.

Thanks.
