Access attribute assigned to this volume. These attributes can be assigned using the RAID
Manager (RAID Manager). Attribute
•
Read/Write: Both read and writer operations are permitted on the logical volume.
•
Read-only: Read operations are permitted on the logical volume.
•
Protect: Neither read nor write operations are permitted.
Volume emulation types. Emulation
Capacity of each volume in GB to two decimal places. Capacity
Indicates whether the volume can be specified as a secondary volume (S-VOL). You can
also use the RAID Manager to specify whether each volume can be used as an S-VOL. S-VOL
Indicates the method that can be used to make LU path and command device settings. Reserved
•
Hyphen (-): Both RAID Manager and Remote Web Console can be used to make LU
path and command device settings.
• RAID Manager: Only RAID Manager can be used to make LU path and command device
settings. Remote Web Console cannot be used to do so.
Period (in days) when you are prohibited from changing access attribute to read/write.
The retention term can be extended but cannot be shortened. During the retention term,
you can change read-only to protect, or vice versa. Retention Term
•
500 days. Attempts to change access attribute to read/write are prohibited in the next
500 days.
•
Unlimited: The retention term is extended with no limits.
• 0 days: You can change access attribute to read/write.
Caution: In Data Retention, you can increase the value for Retention Term, but cannot
decrease the value.
Number of LU paths. Path
Indicates the mode that the RAID Manager user assigns to the volume. You cannot use
Remote Web Console to change modes. You must use the RAID Manager to change modes. Mode
•
Zer: Zero Read Cap mode is assigned to the volume. If the Read Capacity command
(which is a SCSI command) is issued to a volume in Zero Read Cap mode, it will be
reported that the capacity of the volume is zero.
•
Inv: Invisible mode is assigned to the volume. If the Inquiry command (which is a SCSI
command) is issued to a volume in Invisible mode, it will be reported that the volume
does not exist. Therefore, the hosts will be unable to recognize the volume.
