Frequently warning PD Reset with RES2CV240 SAS Expander

Jump to solution

I have a RAID 6 array with 10 2TB SATA HDDs attach to RES2CV240(ph13 F/W).

And I use Hard Disk Sentinel to monitor HDDs' SMART status.

When HD Sentinel start or refresh status (default 5 minutes), the MegaRAID Storage Manager shows several warnings and informations, like:

Controller ID: 0 Unexpected sense: PD = 8-Invaild field in CDB, CDB = 0x5a 0x00 0x1c 0x00 0x00 0x00 0x00 0x00 0xfc 0x00, Sense: 0x70 0x00 0x05 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x24 0x00 0x00 0x00 0x00 0x00

Controller ID: 0 PD Reset: PD = 8, Error = 3, Path = 0x5001E673D9DDDFFD

The TTY Log is:

When it happed, the read and writh speed of the array drop to ~10MB/s, as normal is ~500MB/s.

Both LSI MegaRAID 9260-8i and LSI Nytro MegaRAID 8110-4i have the same situation.

 

Is there any solution?

Or just the RES2CV240 can not handle a SATA PIO command?

Hello,

 

 

We notice that you are using LSI RAID controllers. Intel RAID expanders are validated to work only with Intel RAID controllers reason why we recommend opening a ticket with LSI* since the issue could be related to compatibility between the components.

YES

Under AAXRMS2LL080 is OK.

But I need advanced RAID function.
