Function

The ldconfig command is used to modify properties of a logical drive.

Format

ipmcset -t storage -d ldconfig -v <control_id> <ldid> <[-name <ldname>] [-rp <rpvalue>] [-wp <wpvalue>] [-iop <iopvalue>] [-ap <apvalue>] [-dcp <dcpvalue>] [-bgi <bgistate>] [-boot] [-sscd <sscdstate>]

Parameters

Parameter	Description	Value
control_id	Specifies the ID of the RAID controller.	0 to 255
ldid	Specifies the ID of the logical drive to be modified.	0 to 255
ldname	Specifies the name of the logical drive to be modified.	The parameter value cannot exceed 15 characters.
rpvalue	Specifies the read policy of the logical drive.	ra: sets the read policy of the logical drives to Read Ahead. nra: sets the read policy of the logical drives to No Read Ahead. NOTE: This parameter is not supported if the logical drive type is CacheCade.
wpvalue	Specifies the write policy of the logical drive.	wt: sets the write policy of the logical drives to Write Through. wb: sets the write policy of the logical drives to Write Back. wbwithbbu: sets the write policy of the logical drives to Write Back with BBU.
iopvalue	Specifies the IO policy of the logical drive.	cio: sets the I/O policy of the logical drives to Cached IO. dio: sets the I/O policy of the logical drives to Direct IO. NOTE: This parameter is not supported if the logical drive type is CacheCade.
apvalue	Specifies the access policy of the logical drive.	rw: sets the access policy of the logical drives to read/write. ro: sets the access policy of the logical drives to read-only. blocked: sets the access policy of the logical drives to blocked. NOTE: This parameter is not supported if the logical drive type is CacheCade.
dcpvalue	Specifies the cache policy of the logical drive.	enabled: enables cache for logical drives. disabled: disables cache for logical drives. default: uses the default policy, which is determined by the cache policy of the member drives. NOTE: This parameter is not supported if the logical drive type is CacheCade.
bgistate	Specifies the BGI status of the logical drive.	enabled: enables the background initialization function for the logical drives. disabled: disables the background initialization function for the logical drives. NOTE: This parameter is not supported if the logical drive type is CacheCade.
sscdstate	Specifies the setting of SSD Caching (whether to use the CacheCade drive as the cache).	enabled: enables the SSD caching function for the logical drives. disabled: disables the SSD caching function for the logical drives. NOTE: The current RAID controller card must have a CacheCade logical drive available. This parameter is unavailable when the logical drive type is CacheCade.

Usage Guidelines

If the command contains -boot, the logical drive is the boot device.

This command can be used only when the following conditions is met:

The RAID controller card supports iBMC out-of-band management. You can refer to the Technical Specifications section in the RAID controller card user guide to determined whether the RAID card supports the iBMC out-of-band management.

Example

# Modify the properties of logical drive 1 under RAID controller 0.

iBMC:/-> ipmcset -t storage -d ldconfig -v 0 1 -name example -rp ra -wp wb -ap rw -iop cio -dcp enabled –bgi enabled -boot
WARNING: The operation may have many adverse effects.
