omreport device data in a world without OMSA on Linux

Looks like RACADM is available independently of OMSA and has some interesting commands, but so far none have the device name that Linux uses to tie back to the virtual disk/RAID name.

Hi,

Yes, RADACM is the only one that I can think of, to generate an output. You can try # racadm raid get vdisks -o in Linux and add grep -E with the desired information that you need. I don't have a server to test the command output, but if it does able to display the desired output, please let us know. 

I cannot seem to locate an option to include the "device name" using racadm that omreport offers.  This is the only way to determine what device to use when creating logical volumes for those servers where I have requirements to separate data onto different disks.

Sorry this is so ugly... I pick "Courier New" for the font but after I post it puts it back to System Font which is just quite disappointing.

Hi,

Can you try

# racadm raid get vdisks -o | grep -E "ID|Name|Size|RAID Level|Read Policy|Write Policy|Device Name"

@DELL-Joey C​ The racadm command does not return the "Device "Name field so the grep command cannot show it.  If you look in the jumbled output that I posted you will notice that "Device Name" is not there.

I did replace "storage" with "raid" and the output is identical as I expected.  The documentation for racadm (v1.25) does not share any other command line arguments that might retrieve the Device Name.

Hello,

Can you check your iDRAC and BIOS firmware are up to date.

Also current iSM and DRAC tools?

These are for 14Gen servers. I'm not sure what server you have.

Dell iDRAC Service Module (iSM) for Linux, v5.3.1.0

Version: 5.3.1.0, A00

Release date: 02 Jul 2024

https://dell.to/3VY55ek

Dell iDRAC Tools for Linux, v11.2.0.0

Version: 11.2.0.0, A00

Release date: 24 Jun 2024

https://dell.to/4cvcHM9

Hello,

I just heard back from one of our Systems Management engineers.

Currently the DRAC tools do not show Device Name.

Maybe a future release could have that feature.

I'll send you a Private Message

@DELL-Charles R​ I updated the firmware on the 16th Generation PowerEdge R760s last week on 6/30.  I do not see newer versions in Repo Manager.  I am using the same versions you shared after having downloaded them by serial number.  The links you shared for the older generation are the same versions.

I just installed RHEL 8.8 from Red Hat media on the 2nd of the servers and duplicated the issue again just to eliminate steps I previously performed that might have interfered.

1. Install RHEL 8.8 OS with minimal setup and reboot.
2. Install dependencies for iDRAC Service Module
3. Install iDRAC Service Module - selected ALL features for testing purposes and to rule out that I may have missed something since I did a selective install before.  Port 1266.  Received message that ISM communication with iDRAC was successful.
4. Install RACADM tool.
5. Rebooted server (I don't believe I did that before...its Linux not icky Windows).
6. Verified within iDRAC that it was talking to ISM...
7. Run command you shared and it does not show the device name.
8. Ran lsblk command to show the device is there.

Hello Eddie,

Thank you for the update.

If you like to submit the information requested on the Private Message I sent then I can get it submitted as a feature enhancement on a future release of DRAC tools.

@DELL-Charles R​ Thanks for your assistance!  I am rather surprised this feature was not implemented when the decision was made to retire OMSA.  The output from omreport is very handy for those cases where you might have some special requirements like I have on these servers or when you inherit a server where you can trying to figure out what on earth the prior person did. 8-)

Hello Eddie,

Thank you again for the information. I have submitted it to the Systems Management team.

We only used the Private message for your private information, Service Tag.

Ongoing discussion can occur here on the forum page.

Hello Eddierowe,

Yes currently there is no equivalent command with required attribute in any other CLI console other than OM.

In ISM also there is no equivalent command which can fetch the current details like Device name.

However tried from PERC CLi utility also to see if this fetches the required details.

Below is the output:

Command  "/opt/MegaRAID/perccli/perccli64 /c0/e32/s0 show all":

Controller = 0
Status = Success
Description = Show Drive Information Succeeded.

Drive Information :
=================
  Drive /c0/e32/s0
  Vendor Id = DELL
  Product Id = PERC H710
  Product Revision = 3.13
  Serial No = XYZ456
  Device Type = Disk
  Size = 931.51 GB
  State = Online
  Stripe Size = 64 KB
  Read Policy = Read Ahead
  Write Policy = Write Back
  Cache Policy = Not Applicable
  Disk Cache Policy = Enabled
  Encryption = Not Applicable
  Bad Blocks = No

Thanks,

Karthik, I wish I had received notifications for replies as I returned today to share what I learned...a PERCCLI command that will spit out all of the virtual drives the server, including the info one would need to tie the two together.

PERCCLI Version = 007.2616.0000.0000 Dec 06, 2023

Command I ran:  ./perccli64 /c0/vall show all

This command gives you the OS Drive Name field which is the device name for Linux such as /dev/sda, /dev/sdb, etc.
