Device Behavior After Controller Reinitialization
When a controller reinitialization occurs in a multiple host VAXcluster system,
the hosts automatically reconnect to the devices attached to the controller. With
OpenVMS operating system versions (both VAX and Alpha), these reconnections
may be via another host. This behavior is not unique to the HSJ array controller
and may be changed in a future version of the OpenVMS operating system.
Maximum Byte Count for ERASE Commands
As of HSOF Version 1.1, the HSOF enforces a maximum byte count corresponding
to 4,194,303 blocks (about 2 gigabytes) for ERASE commands. OpenVMS facilities
that rely on these commands automatically adjust to this behavior. This is only
of concern for applications that issue these commands directly.
The following subsections are limitations and clarifications of the OpenVMS and
VAX VMS operating system for HS array controller support.
8.3.2.1 HSJ and HSD30 Array Controller Disks as Initialization Devices
The HSJ and HSD30 array controllers have certain restrictions when used with
specific systems. Those restrictions are described in the following sections.
VAX 7000 and VAX 10000 Systems
HSJ array controller operating firmware Version 1.1 and later supports manual
and automatic initializing for VAX 7000/10000 systems. For a disk drive
connected to an HSJ array controller to be both a VAX 7000/10000 manual
and automatic initialize device, the following conditions must be met:
1. VAX 7000/10000 console code must be at Version 3.2 and include the ‘‘Single
Path’’ patch. Later versions of the console code include the patch.
2. HSOF must be at Version 1.1 or greater for HSJ40 array controllers and
Version 1.4 for HSJ30 array controllers.
Note
Contact your Digital Multivendor Customer Services representative if
you need to upgrade your VAX 7000/10000 console code to Version 3.2 or
greater.
Currently, HSD30 array controller-attached devices are not supported as
manual or automatic boot devices.
If your VAX 7000/10000 console code version is earlier than Version 3.2, you are
limited to manual initializing. To manually initialize your system, perform the
following steps:
1. Ensure that the disk drives attached to the HSJ array controller are visible
to the boot driver by entering the SHOW DEVICE command repeatedly (from
the virtual console) until the disk drives attached to the HSJ array controller
are reported (usually two repetitions are sufficient).
2. Enter the default initialize device string. (Refer to the VAX console
instructions in the VAX console documentation.)
3. Enter the INITIALIZE command.
