1. $ decram create disk mdf1111 /capacity=16777216 /memory=local - /serve /nopersist /rad=2 This example creates an 8 gigabyte memory disk mdf1111 in local memory with an allocation class equivalent to the node allocation class. It is issued from the VMS prompt. It will not persist at the next reboot but disk serving to the VMScluster is enabled. If the system has RAD SUPPORT enabled then RAD 2 will be used to create the disk otherwise OpenVMS will pick the RAD(s). 2. DECRAM> create disk mda0 /cap=1000034 /mem=shared /rad=(0,1) This example creates memory disk $99$mda0 in shared memory RAD 0 and RAD 1 with a size of 1,000,034 blocks and allocation class 99. It is issued from the DECRAM> prompt. It will persist at the next reboot but disk serving to the VMScluster is not enabled. 3. DECRAM> create disk mdb0 /cap=10000 /mem=shared /alloc=13 DECRAM> create disk mdb1 /cap=10000 /mem=shared /alloc=13 $ init $13$mdb0 $13$mdb0 $ mount dsa0: /shadow=($13$mdb0:,$13$mdb1:) $13$mdb0 This example creates two 10000 block shared memory disks with allocation class 13. One of them is initialized and a VMS Volume shadow set is made from the two memory disks. The memory disks are not served to the cluster. 4. VMS Galaxy Instance 0 $ decram create disk mdb0 /capacity=10000 /memory=shared $ init mdb0 mdb0 $ mount /cluster mdb0 mdb0 $ show device mdb0 Device Device Error Volume Free Trans Mnt Name Status Count Label Blocks Count Cnt $99$MDB0: (BANG) Mounted 0 MDB0 9967 1 2 VMS Galaxy Instance 1 $ decram create disk mdb0 /capacity=10000 /memory=shared $ show device mdb0 Device Device Error Volume Free Trans Mnt Name Status Count Label Blocks Count Cnt $99$MDB0: (BIG1) Mounted 0 MDB0 9967 1 2 This example assumes a two instance VMS Galaxy with DECRAM V3 installed on both instances. It creates two 10000 block shared memory disks with allocation class 99. One of them is created on instance 0 and the other on instance 1. The shared disk is initialized and mounted cluster-wide from instance 0. Note that if a shared disk has been created on each instance the "$ decram create disk" command is only necessary on one instance.
