HP Server hangs after SSD installation

[Karthik_Tel]

Hi Team,

We are using HP DL380 G7 hardware for all our servers and SLES 10 X86_64 is our OS. Recently we have installed SSD drives on all our servers in order to improve the performance. Unfortunately after SSD installation, our servers are showing a strange behaviour which is, whenever we try to run the jobs, the server goes to the hang state. We couldn't able to get much logs from the server but based on the analysis with SAR report, we could see that load_avg of the servers spikes limitless during while the server hangs. SSD Drive details - 800Gb SAS 6G SFF Enterprise SSD.

"Note: Issue happens while we run the batch jobs and all our batch jobs are ETL based running on Infosphere Datastage 9.1 version. Before installing the SSD, we used HP 900GB 6G SAS 10K 2.5in DP ENT HDD drive and we didnt face this issue."

Kindly shed some lights for us to resolve this issue please. Any further details required, please let me know
