■ When the migration destination volume is "WSV"
When changing the number of concatenations for a WSV, check "Wide Stripe Size" for the WSV, the
specifications of the existing RAID groups (RAID level, Stripe Depth, drive type, disk speed, and number of
member drives), and the RAID group number of all the concatenated RAID groups. The following describes
how to check the specifications.
(1)
Click the [No.] link or the [Name] link of the migration source WSV in the volume list.
(2)
A detailed information screen for the WSV is displayed. Check "Wide Stripe Size" in the [Basic] tab
screen.
(3)
Click the [Used RAID Group] tab to display the concatenation information of the WSV. Check "RAID
Group No." and "Concatenation Order" that are configured for the WSV. The display order of the RAID
group information indicates the "Concatenation Order".
(4)
Filter the RAID group list by the RAID group number that configures a WSV, and then click the [No.]
link or the [Name] link of the RAID group. Any RAID group can be specified because the RAID groups
in the WSV have the same specifications.
(5)
A detailed information screen for the RAID group is displayed. Check "RAID Level" and "Stripe Depth"
in the [Basic] tab screen.
(6)
Click the [Drive] tab to display the information of the drives that are configured for the RAID group.
Check "Type", "Speed", and "Number of Member Drives". For "Number of Member Drives", use the
displayed number of drives.
