[Linux-PowerEdge] PERC H700 activate disk without reboot

Alex, the H700 requires drives to be a part of a virtual disk.
It sounds like in this case you would want to create a single-disk RAID0 to present the drive to the OS

The options and syntax for that operation can be found here

Follow that up with an initialization of that new virtual disk. Be sure to specify the correct virtual disk.

List virtual disks
omreport storage vdisk controller=0

Initialize virtual disk
omconfig storage vdisk action=initialize controller=0 vdisk=ID

Subject: [Linux-PowerEdge] PERC H700 activate disk without reboot


After inserting a new disk to Dell PE R710 with PERC H700 adapter I can see it via omreport or with megacli tool, but can not make it visible to the system - Debian Wheezy with kernel 3.2.61.

After issuing host_rescan:

  echo '- - -'  >/sys/class/scsi_host/host0/scan

I see in dmesg that the disk is recognized by the kernel, but still do not see it in fdisk/lsblk.. output.

I noticed that omreport shows the new disk status as Ready and not Online, but it seems that I can not change the status using omconfig:

   omconfig  storage pdisk action=online controller=0 pdisk=1:0:4
   Operation disabled. Read, action=online
   Refer to the documentation for more information.

megacli fails here too:

   megacli -PDOnline -PhysDrv [32:4] -a0

   Adapter: 0: Failed to change PD state at EnclId-32 SlotId-4.

   Exit Code: 0x01

Is there a way to activate the disk without rebooting the server ?

Thank you,
