LUN Security Extension
HP StorageWorks LUN Security XP Extension is an optional feature that
prevents hosts from writing to protected volumes. This is similar to the
ORACLE Data Validation command, setting a protection attribute for a
specified LU.
Guarding options
RAID Manager supports the following guarding options:
Hiding from inquiry commands
. RM conceals the target volumes from
SCSI Inquiry commands by responding “unpopulated volume” (0x7F) to
the device type.
“SIZE 0” volume
. RM replies to SCSI Read Capacity commands with
“SIZE 0” for the target volume.
Read protection.
RM protects volumes from reading by responding with
the check condition of “Illegal function” (SenseKey=0x05,
SenseCode=0x2200).
Write protection.
RM protects volumes from writing by replying with
“Write Protect” in the Mode sense header and by responding with the check
condition of “Write Protect” (SenseKey=0x07, SenseCode=0x2700).
S-VOL disabling.
RM protects volumes from becoming an S-VOL during
pair creation.
Commands affected
RAID Manager has options in the following three commands for setting
and verifying guarding:
raidvchkset
. This command sets the parameters for guarding specified
volumes.
