VAX 4300 disk logicals change

[Nahmad_1]

Hi There

We have an old VAX 4300 with VMS 5.5. I want to baseline it from the tapes (including vms and application) as VMS is corupt now. It used to display its disk like $1$DIA0 but now as R2UZZA$DIA0. Is there any way to change it to $1$DIA0 on the >>>> ?

Thanks in Advance

Ahmad,

seems like you've swapped the DSSI disk. You can set the ALLCLASS parameter in the DSSI ISE.

This is described here:

Volker did a typo, it is
ALLOCLASS

[Volker Halle]

Gerard,

ALLOCLASS is the OpenVMS system parameter name.

ALLCLASS is the parameter name on the DSSI ISE.

The DSSI disk contains a MSCP server and - by default (ALLCLASS=0) - uses it's NODENAME to present the disk. If ALLCLASS is .NE. 0, it will present the disk using $n$DIAx: with n being the allocation class number (ALLCLASS).

Hi,

Steps to implement Volkerâ s above explanation.

Try this.

$ mc sysgen
SYSGEN> SHOW ALLOCLASS
Parameter Name Current Default Min. Max. Unit Dynamic
-------------- ------- ------- ------- ------- ---- -------
ALLOCLASS 0 0 0 255 Pure-numbe
SYSGEN>
SYSGEN> USE CURRENT
SYSGEN> SET ALLOCLASS 1
SYSGEN> WRITE CURRENT
SYSGEN> SHOW ALLOCLASS
Parameter Name Current Default Min. Max. Unit Dynamic
-------------- ------- ------- ------- ------- ---- -------
ALLOCLASS 1 0 0 255 Pure-numbe
SYSGEN>EXIT

ALLOCLASS is not dynamic parameter. Hence you need to reboot the machine after setting the ALLOCLASS parameter.

Ketan,

Ahmad is talking about the DSSI device name as shown on the console prompt >>>

This does NOT involve the OpenVMS ALLOCLASS system parameter at all.

The ALLCLASS parameter in the DSSI ISE needs to be changed.

Ok, Sorry about that.

For both this cited host allocation case and for the allocation classes that are present in storage controllers such as the ISE/DSSI and HSC/CI and EVA series storage controllers, you may (will) need to reboot the whole cluster to get the allocation classes reset; to get references to the old classes removed from the cluster.
