ramdiskadm
ramdiskadm(1M) System Administration Commands ramdiskadm(1M)
NAME
ramdiskadm - administer ramdisk pseudo device
SYNOPSIS
/usr/sbin/ramdiskadm -a name size [g | m | k | b]
/usr/sbin/ramdiskadm -d name
/usr/sbin/ramdiskadm
DESCRIPTION
The ramdiskadm command administers ramdisk(7D), the ramdisk driver. Use ramdiskadm to create a new named ramdisk device, delete an existing
named ramdisk, or list information about existing ramdisks.
Ramdisks created using ramdiskadm are not persistent across reboots.
OPTIONS
The following options are supported:
-a name size Create a ramdisk named name of size size and its corresponding block and character device nodes.
name must be composed only of the characters a-z, A-Z, 0-9, _ (underbar), and - (hyphen), but it must not begin with a
hyphen. It must be no more than 32 characters long. Ramdisk names must be unique.
The size can be a decimal number, or, when prefixed with 0x, a hexadecimal number, and can specify the size in bytes (no
suffix), 512-byte blocks (suffix b), kilobytes (suffix k), megabytes (suffix m) or gigabytes (suffix g). The size of the
ramdisk actually created might be larger than that specified, depending on the hardware implementation.
If the named ramdisk is successfully created, its block device path is printed on standard out.
-d name Delete an existing ramdisk of the name name. This command succeeds only when the named ramdisk is not open. The associated
memory is freed and the device nodes are removed.
You can delete only ramdisks created using ramdiskadm. It is not possible to delete a ramdisk that was created during the
boot process.
Without options, ramdiskadm lists any existing ramdisks, their sizes (in decimal), and whether they can be removed by ramdiskadm (see the
description of the -d option, above).
EXAMPLES
Example 1 Creating a 2MB Ramdisk Named mydisk
# ramdiskadm -a mydisk 2m
/dev/ramdisk/mydisk
Example 2 Listing All Ramdisks
# ramdiskadm
Block Device Size Removable
/dev/ramdisk/miniroot 134217728 No
/dev/ramdisk/certfs 1048576 No
/dev/ramdisk/mydisk 2097152 Yes
EXIT STATUS
ramdiskadm returns the following exit values:
0 Successful completion.
>0 An error occurred.

NOTES
The abilities of ramdiskadm and the privilege level of the person who uses the utility are controlled by the permissions of
/dev/ramdiskctl. Read access allows query operations, for example, listing device information. Write access is required to do any state-
changing operations, for example, creating or deleting ramdisks.
As shipped, /dev/ramdiskctl is owned by root, in group sys, and mode 0644, so all users can do query operations but only root can perform
state-changing operations. An administrator can give write access to non-privileged users, allowing them to add or delete ramdisks. How-
ever, granting such ability entails considerable risk; such privileges should be given only to a trusted group.
