Hitachi Compute Blade 500 Series - Initializing virtual drives

Initializing virtual drives
This section describes how to initialize virtual drives. You can use two types
of initialization are available, Fast Initialization and Full Initialization,
depending on the operational condition.
Select a procedure referring to For fast initialization on page 6-25 and For
full initialization on page 6-25 for details.
Note: Initializing virtual drives will corrupt data on the drives, including
virtual drive information, which is required for OS operation. Make sure to
back up necessary data before initialization.
Note:
• It takes log hours until Full Initialization is complete with LSI Software
RAID Configuration Utility. Fast Initialization is recommendable except for
on specific conditions.
•
Virtual drives in consistency check or rebuild cannot be initialized. When
each processing is complete, initialize the virtual drive.
For fast initialization
When virtual drives to initialize are on the following conditions, Fast
Initialization is recommendable.
• When reconfiguring and reinitializing virtual drives without the current
RAID level: When reconfiguring and reinitializing RAID 1 virtual drives
with the same RAID 1
•
When reconfiguring and reinitializing virtual drives with RAID 0 or single
physical drive configuration
• When newly configuring and initializing virtual drives after adding SATA
HDD
Note: When virtual drives to initialize are not on conditions above or you
need to initialize all virtual drive area, execute Full initialization procedure on
page 6-31.
For full initialization
When virtual drives to initialize are on the following conditions, Full
Initialization is recommendable.
• When reconfiguring and reinitializing virtual drives after changing the
RAID level from RAID 0 or a single physical drive configuration to RAID 1.
•
When initializing all area of virtual drives
Note: It takes hours for Full Initialization to complete. When conditions
mentioned above are not met, Fast Initialization is recommendable. see Fast
initialization procedure on page 6-26 for details.
