.SH "DESCRIPTION"

\fB(ALPHA)\fR \fBgcloud alpha compute disks update\fR updates a Compute Engine
persistent disk.



.SH "EXAMPLES"

To update labels 'k0' and 'k1' and remove label 'k3' of a disk, run:

.RS 2m
$ gcloud alpha compute disks update example\-disk \e
  \-\-zone=us\-central1\-a \-\-update\-labels=k0=value1,k1=value2 \e
  \-\-remove\-labels=k3
.RE

.RS 2m
`_k0_` and `_k1_` are added as new labels if not already present.
.RE

Labels can be used to identify the disk. To list disks with the 'k1:value2'
label, run:

.RS 2m
$ gcloud alpha compute disks list \-\-filter='labels.k1:value2'
.RE

To list only the labels when describing a resource, use \-\-format to filter the
result:

.RS 2m
$ gcloud alpha compute disks describe example\-disk \e
  \-\-format="default(labels)"
.RE

To append licenses to the disk, run:

.RS 2m
$ gcloud alpha compute disks update example\-disk \e
  \-\-zone=us\-central1\-a \e
  \-\-append\-licenses=projects/license\-project/global/licenses/\e
license\-1,projects/license\-project/global/licenses/license\-2
.RE

To remove licenses from the disk, run:

.RS 2m
$ gcloud alpha compute disks update example\-disk \e
  \-\-zone=us\-central1\-a \e
  \-\-replace\-licenses=projects/license\-project/global/licenses/\e
license\-1,projects/license\-project/global/licenses/license\-2
.RE

To replace a license on the disk, run:

.RS 2m
$ gcloud alpha compute disks update example\-disk \e
  \-\-zone=us\-central1\-a \e
  \-\-replace\-license=projects/license\-project/global/licenses/\e
old\-license,projects/license\-project/global/licenses/new\-license

\fB\-\-access\-mode\fR=\fIACCESS_MODE\fR

Specifies how VMs attached to the disk can access the data on the disk. To grant
read\-only access to multiple VMs attached to the disk, set access\-mode to
READ_ONLY_MANY. To grant read\-write access to only one VM attached to the disk,
use READ_WRITE_SINGLE. READ_WRITE_SINGLE is used if omitted. \fIACCESS_MODE\fR
must be one of: \fBREAD_ONLY_MANY\fR, \fBREAD_WRITE_MANY\fR,
\fBREAD_WRITE_SINGLE\fR.

.TP 2m
\fB\-\-add\-guest\-os\-features\fR=\fIADD_GUEST_OS_FEATURES\fR

Specifies guest OS features to add to the disk. Refer to
https://cloud.google.com/compute/docs/images/create\-custom#guest\-os\-features

value is supported): \fBGVNIC\fR.

.TP 2m

Size of the disks. The value must be a whole number followed by a size unit of
\f5\fIGB\fR\fR for gigabyte, or \f5\fITB\fR\fR for terabyte. If no size unit is
specified, GB is assumed. For details about disk size limits, refer to:
https://cloud.google.com/compute/docs/disks

.TP 2m
\fB\-\-update\-labels\fR=[\fIKEY\fR=\fIVALUE\fR,...]

List of label KEY=VALUE pairs to update. If a label exists, its value is
modified. Otherwise, a new label is created.

Keys must start with a lowercase character and contain only hyphens (\f5\-\fR),
underscores (\f5_\fR), lowercase characters, and numbers. Values must contain
only hyphens (\f5\-\fR), underscores (\f5_\fR), lowercase characters, and
numbers.

.TP 2m
\fB\-\-append\-licenses\fR=\fILICENSE\fR,[\fILICENSE\fR,...]

"A list of license URIs or license codes. These licenses will be appended to the
existing licenses on the disk. Provided licenses can be either license URIs or
license codes but not a mix of both.

.TP 2m
\fB\-\-remove\-licenses\fR=\fILICENSE\fR,[\fILICENSE\fR,...]

A list of license URIs or license codes. If present in the set of existing
licenses, these licenses will be removed. If not present, this is a no\-op.
Provided licenses can be either license URIs or license codes but not a mix of
both.

.TP 2m
\fB\-\-replace\-license\fR=\fILICENSE\fR,\fILICENSE\fR

A list of license URIs or license codes. The first license is the license to be
replaced and the second license is the replacement license. Provided licenses

\fB\-\-clear\-architecture\fR

Removes the architecture or processor type annotation from the disk.

.TP 2m
\fB\-\-update\-architecture\fR=\fIUPDATE_ARCHITECTURE\fR

\fB\-\-region\fR=\fIREGION\fR

Region of the disk to update. If not specified, you might be prompted to select

To avoid prompting when this flag is omitted, you can set the
\f5\fIcompute/region\fR\fR property:

$ gcloud config set compute/region REGION
.RE

A list of regions can be fetched by running:

.RS 2m
$ gcloud compute regions list
.RE

To unset the property, run:

.RS 2m
$ gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable
\f5\fICLOUDSDK_COMPUTE_REGION\fR\fR.

.TP 2m
\fB\-\-zone\fR=\fIZONE\fR

Zone of the disk to update. If not specified and the \f5\fIcompute/zone\fR\fR
property isn't set, you might be prompted to select a zone (interactive mode
only).

To avoid prompting when this flag is omitted, you can set the
\f5\fIcompute/zone\fR\fR property:
