         #dcli -g ~/all_group -l root "imagehistory" > imagehistory.txt

• Current IP addresses defined for all Exadata Storage Servers and database servers using the following command

         #cellcli -g ~/all_group -l root "ifconfig" > ifconfig_all.txt

• Information about the configuration of the cells, cell disks, flash logs, and IORM plans using the following commands

        #dcli -g ~/cell_group -l root "cellcli -e list cell detail" > cell_detail.txt

        #dcli -g ~/cell_group -l root "cellcli -e list physicaldisk detail" > \

        physicaldisk_detail.txt

        #dcli -g ~/cell_group -l root "cellcli -e list griddisk attributes \

        name,offset,size,status,asmmodestatus,asmdeactivationoutcome" > \           griddisk.txt

        #dcli -g ~/cell_group -l root "cellcli -e list flashcache detail" > \

        fc_detail.txt

        #dcli -g ~/cell_group -l root "cellcli -e list flashlog detail" > fl_detail.txt

        #dcli -g ~/cell_group -l root "cellcli -e list iormplan detail" > \

        iorm_detail.txt

• HugePages memory configuration on the database servers using the following command

        #dcli -g ~/dbs_group -l root "cat /proc/meminfo | grep 'HugePages'" >\          hugepages.txt

• InfiniBand switch information using the following command

        #ibswitches > ibswitches.txt
