Administration and Diagnostics Utilities - Oracle Exadata Recipes: A Problem-Solution Approach - page 172

How It Works
Oracle's sundiag.sh utility is used to generate server diagnostics and is installed in /opt/oracle.SupportTools on
every Exadata Compute Server and Storage Server. When logging Oracle Service Requests, it is common for Oracle
Support to request the output of the sundiag.sh utility so it is important to know where the utility it is, how to run it,
and understand what it does.
On both compute servers and storage cells, sundiag.sh generates the following output:

dmesg command, which contains kernel-level diagnostics from the kernel • The output of the

ring buffer

fdisk -l , which contains a list of all disk partitions

• The output of

lspci , which contains a list of all PCI buses on the system • The output of

lsscsi , which contains a list of all SCSI drives on the system • The output of

MegaCli64 , which provides MegaRAID controller diagnostics • Various outputs of

ipmitool sel elist , which queries the ILOM interface for assorted sensor
readings for all IPMI enabled devices

• The output from

/var/log/messages • A copy of

MegaSAS.log , which provides information about your SAS disks
In addition, when launched from an Exadata Storage Server, sundiag.sh also collected the following information:

• A file called

cellcli list cell detail • The output of

cellcli list celldisk detail • The output of

cellcli list lun detail • The output of

cellcli list physicaldisk detail • The output of

normal state

• The output of all physical disks not in a

cellcli list griddisk detail • The output of

cellcli list flashcache detail • The output of

cellcli list alerthistory • The output of

alert.log , ms-odl.log , and ms-odl.trc files • A copy of your storage cell

/usr/bin/flash_dom -l

• Information about your PCI flash modules, or FDOMs, by using the

command

/opt/oracle/cell/cellsrv/deploy/scripts/unix/hwadapter/diskadp
/scripts_aura.sh , which provides details about your disk adapters

• The output of

/opt/oracle/cell/cellsrv
/deploy/scripts/unix/hwadapter/diskadp/get_disk_devices.pl script
In short, sundiag.sh generates a comprehensive set of diagnostics output, tailored to whether you run it from a
compute node or storage server.
