Storage System Configuration
If you use OS native multipathing software, you must select Use third-party multipath software for the initiator, as shown in Figure 6-5.
The Switchover Mode and Path Type depend on the actual services, as described in Table 6-5.

Host Configuration
Solaris 8 and 9
In Solaris 8 and 9, you must install the multipathing software manually. The software name is StorageTek SAN Foundation and its latest version is SAN 4.4.
You can obtain the software update history and installation guide of each version from the following address:
http://www.oracle.com/technetwork/documentation/san-software-194281.html
Solaris 8 and Solaris 9 are seldom used now and maintenance for them has discontinued.
This section provides the typical configurations of Solaris 8 and 9.
Solaris 8 and 9 do not support ALUA. Therefore, you must disable ALUA on the storage system and set the multipathing configuration file. The detailed configurations on the host are as follows:
- Check the HBA driver status.
Run the cfgadm command on the host to check whether the HBA drivers are normal.
bash-3.2# cfgadm Ap_Id Type Reseptacle Occupant Condition C0 scsi_bus connected configured unknown C1 scsi_bus connected unconfigured unknown C2 fc_private connected configured unknown C3 fc_private connected configured unknown
In this example, the types of c2 and c3 are fc-private, representing two HBAs. Both HBAs are connected and their driver status is configured, indicating that the drivers are loaded successfully. If the command output is different from the preceding information, the HBA drivers are not loaded successfully. Run the reboot -r command to reload the HBA drivers.
The HBA type queried by the cfgadm command depends on the networking mode of the HBA. When an HBA connects to a storage system directly, its type is fc-private. When an HBA connects to a switch, its type is fc-fabric.
- Query the vendor ID and product ID of the storage system.
Run the format command on the host. Select a mapped disk and then select inquiry to query the LUN information.

- Add the vendor ID and product ID of the storage system to the /kernel/drv/scsi_vhci.conf file.
scsi-vhci-failover-override = "HUAWEI S5500T", "f_sym",..."HUAWEI S2600T", "f_sym";
In this example, two storage systems are added. Their vendor IDs are HUAWEI and product IDs are S5500T and S2600T, respectively.
The vendor ID must contain eight characters. If the vendor ID is not long enough, use spaces to reach the required length. The product ID has no length limit.
Two pairs of vendor IDs + product IDs are separated by a comma (,). The last pair of vendor ID + product ID ends with a semicolon (;).
- Run vi /kernel/drv/fp/conf to open the file and change mpxio-disable to no. Then save the file and exit.
- Run the stmsboot -e command on the host to activate the STMS function.
The system prompts you to reboot STMS. During the reboot, the /etc/vfstab file and dumping configurations are updated to refresh the device names.
If update //plat is displayed during the reboot, the host is accessing the official server to update the platform.
Solaris 10
In Solaris 10, the multipathing software has been installed by default, but is not enabled.
The host configuration varies, depending on whether ALUA is enabled on the storage system. Use either of the following methods according to your own ALUA settings.
If ALUA Is Enabled on the Storage System
- Install and enable the multipathing software.
After ALUA is enabled on the storage system, run the stmsboot -D fp -e command to enable the multipathing software. You do not need to configure the software on the host.
The following is an example:
bash-3.2# stmsboot -D fp -e WARNING: This operation will require a reboot. Do you want to continue ? [y/n] (default: y) y The changes will come into effect after rebooting the system. Reboot the system now ? [y/n] (default: y) y updating /platform/sun4u/boot_archive
The host restarts after the preceding operation is performed.
After the host restarts, the following LUN information is displayed.
Figure 6-6 LUN information on SolarisThe path format is scsi_vhci, which contains the path information after multiple paths are aggregated.
- Verify the configurations.
After the LUNs are mapped to the host, scan for the LUNs on the host and verify that the numbers and status of the preferred and non-preferred paths are correct. The following is an example:

If ALUA Is Disabled on the Storage System
If ALUA is disabled on the storage system, you must modify the configuration file on the host for the multipathing software to identify the LUNs mapped by the storage system.
- Query the vendor ID and product ID of the storage system.
Run the format command on the host. Select a mapped disk and then select inquiry to query the LUN information.

Note the following in the command output:
- load-balance
Retain the default value round-robin.
- auto-failback
Retain the default value enable.
- Storage information
The default information is as follows:
##device-type-scsi-options-list =#"SUN SENA", "symmetric-option";##symmetric-option = 0x1000000;
In this display, "SUN SENA" indicates the storage information, where SUN represents the vendor ID and SENA represents the product ID.
When configuring the storage information, delete the comment tag (#) and change the vendor ID and product ID to the actual values. The following is an example:
device-type-scsi-options-list = "HUAWEI S5500T", "symmetric-option", "HUAWEI S2600T", "symmetric-option"; symmetric-option = 0x1000000;
In this example, two storage systems are added. Their vendor IDs are HUAWEI and product IDs are S5500T and S2600T, respectively.
The vendor ID must contain eight characters. If the vendor ID is not long enough, use spaces to reach the required length. The product ID has no length limit.
Two pairs of vendor IDs + product IDs are separated by a comma (,). The last pair of vendor ID + product ID ends with a semicolon (;).

- Activate the STMS function on the host.
Run the stmsboot -D fp -e command to activate STMS. The multipathing software takes effect after the host restarts.

The host configuration varies, depending on whether ALUA is enabled on the storage system. Use either of the following methods according to your own ALUA settings.
If ALUA Is Enabled on the Storage System
The configuration method is the same as that of Solaris 10. See Solaris 10.
If ALUA Is Disabled on the Storage System
- Query the vendor ID and product ID of the storage system.

The vendor ID must contain eight characters. If the vendor ID is not long enough, use spaces to reach the required length. The product ID has no length limit.
Two pairs of vendor IDs + product IDs are separated by a comma (,). The last pair of vendor ID + product ID ends with a semicolon (;).
- Run the stmsboot -D fp -e command on the host to activate the STMS function. If STMS has been activated, run the stmsboot -u command to update the configuration file after it is modified.
The system prompts you to reboot STMS. During the reboot, the /etc/vfstab file and dumping configurations are updated to refresh the device names.
If update //plat is displayed during the reboot, the host is accessing the official server to update the platform.

Storage System Configuration
It is advised to disable ALUA. To enable ALUA, do as follows:
- T series V100R005, Dorado2100, Dorado5100, and Dorado2100 G2
Use the Huawei OceanStor ISM system to enable ALUA for all the host initiators, as shown in Figure 6-7.
- T series V200R002, 18000 series, V3 series, and 18000 V3 series
Use the Huawei OceanStor DeviceManager to enable ALUA for all the host initiators, as shown in Figure 6-8.
Multi-controller ALUA is not supported. When there are more than two controllers, ALUA is disabled by default and the ALUA status cannot be changed.
