Access attribute restrictions
Some restrictions apply when you use the following HP XP7 Storage products or functions on a
volume that has an access attribute assigned to it.
Virtual LUN
•
You cannot convert into spaces volumes that do not have the read/write attribute.
•
You cannot initialize customized volumes that do not have the read/write attribute.
RAID Manager
•
You can use RAID Manager to make some Data Retention settings. You can view some of the
RAID Manager settings in the Data Retention user interface.
•
When viewing the Data Retention window, another user might be using RAID Manager to
change an access attribute of a volume. If the RAID Manager user changes an access attribute
of a volume when you are viewing the Data Retention window, you will be unable to change
the access attribute of the volume by using Data Retention. If you attempt to change the access
attribute of the volume by using the Data Retention, an error occurs. If the error occurs, refresh
the display, and then retry changing the access attribute of the volume.
Automatically started software
If any software that can start automatically is enabled, you must do one of the following:
•
Perform Data Retention operations when the program is not running.
•
Cancel the setting of the program start time.
Some software is likely to start automatically at the time specified by the user. For example, if an
Auto LUN user or a Performance Monitoring user specifies the time for starting the monitor, the
monitor will automatically start at the specified time.
Access attributes work flow
Access attribute workflow includes the following steps:
1. “Changing an access attribute to read-only or protect” (page 159)
2. “Changing an access attribute to read/write” (page 161)
3. “Enabling or disabling the expiration lock” (page 161)
4. “Disabling an S-VOL” (page 162)
5. “Reserving volumes” (page 162)
