AVT or non-avt but can operate only in one mode per storage partition. This support is only available on AIX 5. You must convert your existing logical volumes or create new ones. There was no faster storage subsystem benchmarked by the SPC at that time January Otherwise, the Windows Server , Windows Server , or Windows Server server could cause data corruption on that device. Ensure that all hardware and software requirements are met.

The range of supported values for health check interval is seconds. Overview of the SDD 7. Parameters num1 [ num2 ] v v When only num1 is specified, the command applies to the hdisk specified by num1.

Adpt The index number of the adapter. Verify that the path is added correctly. Select Software Maintenance and Utilities and press Enter. Continuing may delete information you may want to keep.

MPIO and SDDDSM dynamic pathing: Storwize V

For fibre-channel-attached devices, enter the following command for each adapter: If the root cause of the path 2 open failure is fixed and you enter the pcmpath open device 23 path 2 command, the following output is displayed: This command will fail if there is any device using the last path attached to this adapter. Otherwise, go to step 3. Change all the child devices of fscsix on your system to the defined state by running the rmdev -l fscsix -R command for all adapters on your system.


IBM storage devices Storage software Storage virtualization. An Install window opens, informing you about suubsystem progress of the IBMsdd software installation.

The output shows that after the swap from site one to site two, SDD selects paths of devices on site two. See Persistent reserve command tools on page 54 for more information.

Examples If you have 12 active ports and decice the pcmpath query port command, the following output is displayed: See Creating the volume group device directory on page Create the group special file.

For information about the fibre-channel adapters that can be used on your AIX host system, go to the following website: This capability prevents a single failing bus adapter on the host system, SCSI or fibre-channel cable, or host-interface adapter on the disk storage system from disrupting data access.

Disk Path P The logical device name assigned by the host. In the example shown in the following output, an additional HBA has been installed: Paths 0 and 2 are the preferred paths. If all retries fail on the preferred controller’s paths, paths on the alternate controller will be selected for retry.

The Publications Center displays prices in your local currency. Examples of valid device model: The disconnected cable must be reconnected within 15 seconds. This new algorithm is applicable only for device models,and Examples If you enter pcmpath set device 2 10 algorithm rr, the path-selection algorithm of hdisk 2 to hdisk 10 is immediately deviice to the round robin algorithm.

Connection The physical location code of supported storage device adapter through which the LUN is accessed.

Determine the size of the logical volume. After this period, one of the nodes performs a target reset and the other node takes over the ownership kbm the devices.
