We see a 600 GB drive partitioned into /dev/sda1 and /dev/sda2 partitions. We know that /dev/sda1 is mounted
to /boot from the df listing, so we also know that the / and /u01 file systems are built on logical volumes. An lsscsi -v
output clues us in that the disks are controlled via an LSI MegaRAID controller:
[root@cm01dbm01 ~]# lsscsi -v
[0:2:0:0] disk LSI MR9261-8i 2.12 /dev/sda
dir: /sys/bus/scsi/devices/0:2:0:0 [/sys/devices/pci0000:00/0000:00:03.0/0000:0d:00.0/host0/
target0:2:0/0:2:0:0]
[root@cm01dbm01 ~]#
Using MegaCli64 we can display the physical hardware:
[root@cm01dbm01 ~]# /opt/MegaRAID/MegaCli/MegaCli64 -ShowSummary -aALL
