Replaced a non-working SAS 5E card in a Dell 2950. Need to remove the old one (HBA) in the Modular Disc Storage Manager.
Not sure out of the two which card has been removed. I know the new one but need to remove the old one then replace with the new one and re-distribute the discs.
I need to identify the removed sas5e card.
Below is what I found for directions but it doesn't tell me which one is the removed one and the card is not removed in the software.
Note: The WWN are NOT written on the SAS controllers, are not displayed in the SAS BIOS and are not visible in OMSA either.
When a SAS 5E is replaced, the WWN are NOT updated automatically.
As a result, replacing a SAS 5E may result in no connectivity to the MD3000 (talking about disk access here). The reason for that is that the WWN presented to the MD3000 are not registered with the new card.
In order to restore the connectivity, open MDSM (since no mapping is involved, a simple SAS connection is enough ; the management port is good too).
Go to the Modify tab and select Edit Host Topology.
Follow those steps:
- For the host where the HBA was replaced, delete the existing mapping for the old HBA:
- Select the host
- Select the HBA Host Port to be deleted
- Click Remove
- Repeat those steps for the second port if applicable
- Add the new HBA ports
- Click Add HBA…
- Select the WWN from the dropdown menu (MDSM will only present un-configured ports; since all the other ports connected to the MD3000 should already be configured, only the WWNs from the new HBA should be displayed). It is expected to see two WWNs, one ending with ‘00’, the other ending with ‘04’.
- Repeat the above steps for the second port is applicable
- Check if the virtual disks are visible from the host again
