We are currently facing the challenge of replacing disks in a raid 1 configuration of a standalone server. The server is quiet old and uses 10k SAS HDD drives together with a Fujitsu D2616 (based on LSI SAS2108). One of the two drives failed. Instead of buying expensive (and compared to SSDs quiet slow) SAS disks, we decided to use SATA SSD drives instead. While replacing the failed disk with the newly inserted SSD, we received an error about not appropriate attributes:
-----------------------------------------------------------------------------
Drive Status ErrCd ErrMsg
-----------------------------------------------------------------------------
/c0/e252/s4 Failure 38 physical disk does not have appropriate attributes
-----------------------------------------------------------------------------
The command we used to replace the disk was:
storcli64.exe /c0/e252/s4 insert dg=0 array=0 row=1
After digging a bit what the issue could be, we found the following under the capabilities section in the output from storcli64.exe /c0 show all
Mix in Enclosure = Allowed
Mix of SAS/SATA of HDD type in VD = Not Allowed
Mix of SAS/SATA of SSD type in VD = Not Allowed
Mix of SSD/HDD in VD = Not Allowed
Which would explain the error received earlier. Since the old disks are SAS HDD and the new ones are SATA SSD.
In this post I found a vague description of changing several capabilities section using a tool called megascu. Sadly I could not find further description nor a download link for megascu. And also I was not able to find a way to change this capabilities with storcli.
Is it possible to change the mix of SAS/SATA and SSD/HDD capabilities of a raid controller or are this fixed values. And if yes, how can they be changed?
Some more information on our setup (from storcli64.exe /c0 show all):
