Method used to enable the BST function in the S2600 V100R001 storage system

Method used to disable the NCQ function for OceanStor S2600 R1: By default, the NCQ function is disabled in OceanStor S2600 R1. Perform operations on the device on which upgrade cannot be performed and the NCQ function needs to be disabled by following instructions in this guide. Each controller has its own NCQ function. On a dual-controller network, you need to disable or enable the NCQ function on two controllers, separately. Check whether the NCQ function is enabled: 1. Log in to the controller as user admin and enter the debug mode (the password is 654321). 2. In the AK-I command line, run lsiutil and enter 1 and 68 in sequence. 3. After step 2, if SATA Native Command Queuing is Enabled, it indicates that the NCQ function is enabled. If SATA Native Command Queuing is Disabled, it indicates that the NCQ function is disabled. Perform the following steps to disable the NCQ function: 1. Run os_test_main.sh -e close to disable the NCQ function. 2. When two controllers are configured, perform the preceding step 1 and step 2 on the peer-end controller. 3. Check whether the NCQ function is enabled by running lsiutil and enter 1 and 68 in sequence in the AK-I command line. If yes, the value of SATA Native Command Queuing is Disabled. 4. After the NCQ function is disabled successfully, start host services.

Whether disk intermixing is supported by S5000/S2600 storage systems: Yes. S2600 storage systems support the intermixing of SAS and SATA disks. However, the intermixing of coffer disks and disks in the same RAID group is not supported. The S5000 supports the intermixing of Fibre Channel disks, SATA disks, and SSDs within or across controller enclosures or disk enclosures. Note: It is recommended that Fibre Channel disks or SSDs be used for coffer disks for S5600 storage systems. If SATA disks are used as coffer disks for S5600 storage systems, data loss may occur in the case of unexpected power failures. The intermixing of the other 20 disks is supported. That is, Fibre Channel disks, SATA disks, or SSDs can be configured.
