3-4 Preparing for Cache Manager Operations
Hitachi Cache Manager User’s Guide
Launching Cache Manager
Launching HRUDCRX
1. Call the HRUDCRX program. The line count must be from 20 to 99, and the
default value is 60. See Figure 3-3 for an example.
2. Use the DD statement to define the volume type. The operand of the
statement must specify the unit and volume, and the DISP operand must
specify OLD.
Note: If more than one DD statement is defined, only the first one will be
processed. If you need to include more than one DD statement, you must
divide the job step.
3. The RAIDPARM DD statement specifies a sequential dataset to describe the
device address when you use STATUS and COUNTS commands with DKC
parameter. The DCB information of the dataset is as follows:
– Dataset format (DSORG): SAM (PS)
– Record format (RECFM) Fixed or Fixed Block (F or FB)
– Record Length (LRECL) 80
– Block Length (BLKSIZE) 80 x n
– You can specify up to 1024 devices.
4. The format and parameter requirements of the RAIDPARM dataset is as
follows:
– RAIDUNIT (CCUU [ - CCUU] [, CCUU] [, ...] )
– You can specify up to 1024 devices.
– The record size is 80 bytes, but you can only use columns 1 through 71.
Data in columns 72 through 80 will be ignored.
– You may not put a space between the comma, hyphen, bracket or
parameter.
– The description must be on one line, with no comments on that line.
– The device number may contain either 3 or 4 digits.
– If you use a hyphen to specify device number, you must put the lesser
number to the left and use the same CC value. All device numbers that
are between the two numbers will be included.
5. The SYSPRINT DD statement specifies a sequential dataset to store the
output messages. The record length must be 132-byte fixed-length record
format.
6. The SYSIN DD statement must specify a dataset that includes HRUDCRX
commands, and the record length must be 80 byte fixed-length record
format of SAM or PAM. Note: HRUDCRX will return normal end (CC=0),
even though user does not specify a command and parameter in the SYSIN
DD statement.
