ATTO Technology SC 5700 RGPreFetch, RGRebuild, RGResumeConversion, RGResumeErase, RGResumeRebuild

RGPreFetch

Specifies the prefetch value for all RAID groups or for the specified RAID Group.

Default: 0

set RGPreFetch [GroupName all] [1-6] get RGPreFetch [GroupName all]

RGRebuild

SC 5300, 5700

Rebuilds the specified RAID group. If no member is specified, all degraded members are rebuilt. Optional parameter BlockDeviceID allows an available block device to be substituted for the RAID member currently assigned to the MemberIndex.

RGRebuild [GroupName] <MemberIndex> <BlockDeviceID>

RGRebuild

SC 5500

Rebuilds the specified RAID group. If no member is specified, all degraded members are rebuilt. Optional parameter BlockDeviceID allows an available block device to be substituted for the RAID member currently assigned to the MemberIndex. If the RAID level has been set to 6, two RAID group members may be rebuilt at the same time.

RGRebuild [GroupName] <<MemberIndex> <BlockDevID> <and MemberIndex2 <BlockDevID2>>>>

RGResumeConversion

Continues the stopped conversion on the specified RAID group.

RGResumeConversion [GroupName]

RGResumeErase

Continues the erase on the specified RAID group.

RGResumeErase [GroupName]

RGResumeInitialization

Continues a stopped initialization for the specified RAID group.

Set RGresumeInitialization [GroupName]

RGResumeRebuild

SC 5300, 5700

Continues the rebuild(s) on the specified RAID group. If no MemberIndex is specified, all stopped rebuilds on that RAID group are resumed.

RGResumeRebuild [GroupName] <MemberIndex>

RGResumeRebuild

SC 5500

Continues the rebuild(s) on the specified existing RAID group. If no MemberIndex is specified, all stopped rebuilds on that RAID group are continued. For RAID 6 groups, if a MemberIndex is specified, all halted RAID members on the span with that MemberIndex resume as well.

RGResumeRebuild [GroupName] <MemberIndex>

RGSectorSize

Sets or displays the sector size of the specified RAID Group. The desired RAID Group sector size must be evenly divisible by the sector size of any member disk. 512 bytes is the default size for most operating systems. Use 4 KB sectors to enable large volume support (greater than 2 TB) in Windows XP (32-bit).

Default: 512

set RGSectorSize [GroupName] [512-8192] get RGSectorSize [GroupName]

RGSpanDepth

Regulates or displays the span depth on the specified RAID group. The RAID group must be of type RAID 0, 1, 4, 5, 6 or 1+0.

set RGSpanDepth [GroupName] [SpanDepth [1-16]] get RGSpanDepth [GroupName]

RGSpeedRead

Performs look-ahead during reads from RAID group member disks for all or the specified RAID group.

Default: auto

set RGSpeedRead [GroupName all] [enabled disabled auto ]

get RGSpeedRead [GroupName all]

RGUnmap

Removes all mapped partitions for a RAID group from the routing table. The partitions themselves are unaffected, although they are inaccessible to initiators.

RGUnmap [GroupName all]

RGWaitTimeout

Specifies the maximum time in seconds that the system waits to discover previously-configured RAID groups attached to the unit. The time out is used during system boot time and when the BlockDevScan command is issued.

Default: 5

set RGWaitTimeout [1-3600] SaveConfiguration Restart command required get RGWaitTimeout
