Requirements
To enable SHC-OSD to identify a storage system by means of its serial number and the internal number of the logical volume, the latter must be known in the configuration of StorMan on the Management Server. No unit of this storage system need be generated and attached in BS2000 for this purpose.
To enable SHC-OSD to identify a local or remote Symmetrix/VMAX3 by means of its serial number and internal device number, the latter must be known in the configuration of the SYMAPI server. No unit of this storage system need be generated and attached in BS2000 for this purpose.
Addressing the units of storage systems by means of serial and device numbers
The serial number of the storage system is a string which consists of numbers and letters.
The internal device number is a four-character hexadecimal number between 0000 and FFFF.
The internal device number of VMAX3 is a five-character hexadecimal number between 00000 and FFFFF. The specification in BS2000 and SHC-OSD commands always has four characters.
SHC-OSD offers the option of abbreviating the serial number. In the dialog, you need specify only the last three digits since these are usually unique. The serial number is then checked against the configuration currently known to ensure it is unique. If it is not unique, the corresponding command is rejected.
The complete string in the S variables should be used in procedures.
When two storage systems are used in which the last three characters are identical and one of the two is not known in the configuration, SHC-OSD cannot recognize this ambiguity. You should consequently check up front whether only one device with the number concerned is used.
In messages, the UNIT insert that contains the MN for generated devices is empty.
However, other inserts exist which output the serial number and device number (see section "Messages and inserts"). "#" is used as the separator between the serial number and device number. Because the UNIT insert is empty, the message may contain some blanks.
Example
NDE1015 DEVICE 000183600026#0000 NOT DEFINED.
Addresses the ETERNUS DX/AF Units by means of the serial number of the storage system and the internal number of the logical volume.
The syntax below is available for this purpose in the SHC-OSD commands:
UNIT=*BY-STORAGE(SERIAL-NUMBER=<serialnumber>,LOGICAL-VOLUME=<number>)
The serial number of an ETERNUS DX/AF storage system is a ten-character number.
Addresses the Symmetrix/VMAX3 Units by means of the serial number of the storage system and the internal number of the logical volume.
The syntax below is available for this purpose in the SHC-OSD commands:
UNIT=*BY-SYMMETRIX(SERIAL-NUMBER=<serialnumber>,LOGICAL-VOLUME=<number>)
The serial number of a Symmetrix/VMAX3 storage system is a twelve-character number.
