Headline: | While IO and CC continues OS locks up on removal of CacheCade SSD PDs |
Description: | Created a CacheCade by 2 SSD PDs.
Created 2 partial R1 on the same array. Performed Full- init and CC on the R1 VDs. Formatted and mounted the R1 VDs Started IO on the R1s by pound. Started CC on the R1 VDs. While IO and CC on progress removed 2 SSD PDs of the Cache Cade. On removed of 2 SSD PDs from the SSCD array OS locks up by “Fatal Trap 12: page fault while in kernel mode”. Nothing fatal reported in the FW log. Noticed that CC continued and completed fine in the FW log. Issue reproduced twice. All logs and screenshot attached for reference. |
Version of Bug Reported: | 3.96 |
Steps to Reproduce: | Create a CacheCade by 2 SSD PDs.
Create 2 partial R1 on the same array. Start IO on the R1s by IO utility pound. Start CC on the R1 VDs. While IO and CC continues on the R1 VDs remove the SSD PDs of the CacheCade. Test Ref: 10M08_Acceptance FreeBSD 8.0 (32 Bit) (MegaRAID SAS 9260-8i (Castor) _ZEUS (#33593.1) I/O should continue if remove all the PDs from SSCD Test Setup: KVM/Shelf: NORPT IRVINE_I24 KVM_M System: Supermicro X6DH8-G BIOS/Date: Phoenix Technologies LTD Version: 6.00 11/24/2006 CPU: 2 Intel(R) Xeon(TM) CPU 3.00GHz RAM: 4GB OS: FreeBSD 8.0 32 bit (Driver: 3.96) Component: 10M08 Controller: LSI MegaRAID SAS 9260-8i (Castor-B3) (FW PKG: 12.11.0-0001 / FW: 2.110.03-0922) Enclosure: DE5600-SAS Camden (FW: 317) RAID Utility: MegaCli (Ver: 8.00.28) Test Utility: Pound |
Resolution: | This Defect is fixed and checked-in to CC, SSCD Path was not earlier tested properly due to which this bug came.
Reason: We never maintain any entry for SSCD in our driver LD_LIST, but when the AEN comes for SSCD removal, driver was searching for SSCD entry in LD_LIST, unable to find this giving Panic. |
Fix Impact: | Low |
External Behavior Change: | No |
Suggested Testing: | Redo the whole tests |
