gvsVolumeName
16 bytes volumeset name, this does not end with a null character ‘\
gvsCapacity
Volume
capacity in blocks
A
block = 512 bytes
The
total capacity (in bytes) of volumeset are gvsCapacity * 512 bytes
gvsCapacityX
For 64 bit extension
gvsFailMask
Bit mask to indicate the failed drive (bit0 -- drive 0, bit1 --
drive 1 ....)
gvsStripeSize

gvsNewFailMask
For
internal use only
gvsNewStripeSize
The
value when modify this volumeset with new stripe size
In
normal case the gvsStripeSize is equal to gvsNewStripeSize

gvsProgress
Progress for the volume if volume is in
initializing/rebuilding/migrating status
The special value of 4096 means the
initializing/rebuilding/migrating completed
gvsScsi
Pointer to sSCSI_ATTR
that describes the SCSI attributes
gvsMemberDisks

Raid level 3 or 30 if the flag 0x100000
is set in the field gvsVolState |
3 |
Raid level 5 or 50 if the flag 0x100000
is set in the field gvsVolState |
4 |
Raid level 6 or 60 if the flag 0x100000
is set in the field gvsVolState |
5 |
Pass-through |
gvsNewMemberDisks
The value when modify this volumeset with new raid level and
this new raid level can causes the changing of member disks
In
normal case the gvsMemberDisks is equal to gvsNewMemberDisks
gvsNewRaidLevel
The
value when modify this volumeset with new raid level
In
normal case the gvsRaidLevel is equal to gvsNewRaidLevel
gvsRaidSetNumber
