Before You Begin
All SAS-2 devices (hosts, NEMs, and storage modules) must be powered on and functioning correctly in order to be properly discovered and made available for zoning configuration.
Note - You must wait at least five minutes after all SAS-2 devices are powered-on before attempting to assign storage module resources. This allows the CMM zmgtd daemon to discover all SAS-2 devices installed in the chassis.
These instructions assume a network connection to the CMM ILOM.
You must log in to the CMM ILOM CLI as a user assigned the Admin, User Management, Console, Reset and Host Control, and Read Only roles (a,u,c,r,o). These roles are required in order to perform a complete backup of the CMM ILOM configuration.
# ssh –l accountname cmm_ip
Where accountname is the name of a user account with Administrator privileges (such as root) and cmm_ip is the IP address of the CMM.
The login prompt is displayed.
After you have successfully logged in, the prompt will be displayed:
Example output might look like:
version SP firmware version: 126.96.36.199.a SP firmware build number: 201022 SP firmware date: Mon Mar 29 10:39:46 EST 2010 SP filesystem version: 0.1.9
If you do not have the minimum version required, update the CMM ILOM firmware before continuing.
–> cd /STORAGE/sas_zoning/
Example output might look like:
/STORAGE/sas_zoning Targets: Properties: zone_management_state = disabled reset_password_action = (Cannot show property) reset_access_action = (Cannot show property) Commands: cd set show ->
–> set zone_management_state=enabled
You will see a warning. You must enter y when prompted to enable zoning.
********* WARNING ********* Enabling CMM zone management will result in the clearing of all zoning configuration in the installed chassis SAS hardware, and any SAS I/O in progress will be interrupted. Are you sure you want to enable CMM zone management (y/n)? y Set 'zone_management_state' to 'enabled' ->
–> show –level all
You will see a listing of all blades and SAS-2 domain storage resources in the chassis. Make a note of where devices and hosts are and decide how you will divide your storage resources. The following examples will help you interpret the list.
The first listing is an example of what's actually in the chassis (blades and NEMs). BL and NEM numbers represent physical slot numbers in the chassis. Empty chassis blade slots will not be shown:
/STORAGE/sas_zoning Targets: BL0 BL1 BL2 BL3 BL4 BL5 BL6 BL7 BL8 BL9 NEM0 NEM1 Properties: zone_management_state = enabled reset_password_action = (Cannot show property) reset_access_action = (Cannot show property)
Example listing for a host blade:
/STORAGE/sas_zoning/BL0 Targets: Properties: add_storage_access = (Cannot show property) remove_storage_access = (Cannot show property)
Note - Storage internal to the server module, or connected to the server's PCIe ExpressModule accessory slots will not be shown and cannot be zoned using the CMM ILOM utility.
Example listing for a storage module. HDD numbers represent physical slot numbers in the storage module. Empty HDD slots will not be shown:
Note - HDD applies to either mechanical or solid-state disk drives.
/STORAGE/sas_zoning/BL2 Targets: HDD0 HDD1 HDD2 HDD3 HDD4 HDD5 HDD6 HDD7 Properties:
Example listing for a storage module hard disk drive:
/STORAGE/sas_zoning/BL2/HDD0 Targets: Properties: type = Hard Disk disk_type = SAS wwn = 0x5000c50003d3a765, 0x5000c50003d3a766 sas_speed = 6.0 Gbps add_host_access = (Cannot show property) remove_host_access = (Cannot show property)
Example listing for a NEM. The NEM number represents the physical NEM slot number in the chassis:
/STORAGE/sas_zoning/NEM0 Targets: SAS Properties:
Example listing for a SAS-NEM's external SAS ports:
/STORAGE/sas_zoning/NEM0/SAS Targets: PORT0 PORT1 PORT2 PORT3 Properties:
Example listing for one of the external ports of a SAS-NEM. PORT number represents external physical SAS-NEM port labeling:
/STORAGE/sas_zoning/NEM0/SAS/PORT0 Targets: Properties: connected = false wwn = (none) sas_speed = (none) add_host_access = (Cannot show property) remove_host_access = (Cannot show property)
Note - At the release of this document, there is no support for connecting external SAS storage to a SAS-NEM's external SAS ports. Refer to the NEM Product Notes for the latest information on support for the external SAS ports.
Note - Access assignment is mutual. You can assign a storage device to a host, or a host to a storage device. The result is the same.
Removing storage can be done using the methods described above and changing the add_storage_access or add_host_access commands to remove_storage_access or remove_host_access.
-> cd /SP/config
-> set passphrase=passphrase
-> set dump_uri= transfer_method://username:password@ipaddress_or_hostname/directorypath/filename.config
transfer_method can be tftp, ftp, sftp, scp, http, or https.
username is the name of the user account on the remote system. (username is required for scp, sftp, and ftp. username is not used for TFTP, and it is optional for HTTP and HTTPS.)
password is the password for the user account on the remote system. (password is required for SCP, SFTP, and FTP. password is not used for TFTP, and it is optional for HTTP and HTTPS.)
ipaddress_or_hostname is the IP address or the host name of the remote system.
directorypath is the storage location on the remote system.
filename is the name assigned to the backup file.
For complete instructions on using ILOM Backup/Restore, refer to your Oracle Integrated Lights Out Manager (ILOM) 3.0 CLI Procedures Guide.
Once you have backed-up your CMM ILOM configurations, proceed to your host(s) to format and create volumes for host-assigned disks.
