• NAS Sync Image (Required when copying the ﬁle system managed by NAS Sync Image

using Continuous Access XP Journal)

Notes on operations

• UID for user reg

istration and GID for group registration in primary/secondary sites

With Continuo

us Access XP Journal, the ﬁle owner information (UID and GID in the primary site) and

quota and ACL information for each user (UID in the primary site) and group (GID in the primary site)

included in the source ﬁle system are copied to the secondary site. Note the UID for user registration

and GID for group registration in the primary and secondary sites (as explained in the following

sections) when you share the NFS/CIFS and set the quota or ACL in the target ﬁle system.

• Register the same user name (or group name) in both sites. The quota and ACL settings

are also the

same.

For local authentication, assign the same UID (or GID) to the same user name (or group name)

in both sites. For NIS, share the NIS server in both sites. For domain authentication, share the

domain cont

roller.

• Register the same user name (or group name) in both sites. (The quota or ACL settings are

different for each site.)

Set the quotas or ACLs again in the secondary site each time the Continuous Access XP Journal

volume pai

rissplit.

• Register the user (or group) in only one site.

For local authentication, do not assign the target UID (GID) in another site to ensure that the UID is

not overlapped with the UID (or GID) of the another user in the another site.

For NIS, s

hare the NIS server in both sites. For domain authentication, share the domain controller.

• Mounting the NFS client for a ﬁlesystemwhosedataisbackeduponline

If you perform online backup for a ﬁle system accessed by the NFS client by secondary copy, you must

specify NFS version 3 before mounting a NAS Blade ﬁle system on the NFS client. If you specify NFS

version 2, you must specify the hard option before mounting a NAS Blade ﬁle system on the NFS client.

• Limitat

ions on Continuous Access XP operations due to the status of cluster, nodes, and resource

groups

When a cluster is not conﬁgured, the cluster is stopped, nodes are stopped, resource groups are

ofﬂine, and connecting the device ﬁle or creating and mounting a ﬁle system is restricted. Due to

these restrictions, the following operations performed in the target Continuous Access XP Journal

operation also end in error. Therefore, you should not operate the cluster, nodes, and resource

groups during the Continuous Access XP Journal operation. Should problems occur with the cluster,

nodes, or resource groups, ﬁx them immediately.

nt and mount the source ﬁle system during the splitting of a Continuous Access XP

Journal pair volume.

• Connect the target ﬁle system to the NAS package.

•Unmo

unt and delete the target ﬁle system before the Continuous Access XP Journal pair is

resynchronized.

• Notes on changing system conﬁguration during Continuous Access XP Journal operations

When changing the following system conﬁgurations during Continuous Access XP Journal operations,

you must change the RAID Manager XP conﬁguration deﬁnition ﬁ lesinCL1andCL2towhichthe
