Restrictions The following restrictions apply when using ESAM in a cluster system: • You cannot use ESAM pair volumes for SAN boot. • You cannot store OS page files in ESAM pair volumes. • For Windows Server® 2008 R2, ESAM does not support Hyper-V function and Cluster Shared Volumes (CSV) function. • If using software with SCSI-2 Reservation, and SCSI-2 Reservation is registered on the P-VOL, a pair cannot be created or resynchronized if SCSI-3 Persistent Reservation key information is also registered on the S-VOL. If SCSI-2 Reservation or SCSI-3 Persistent Reservation key information are not registered on the P-VOL, but SCSI-3 Persistent Reservation key information is registered on the S-VOL, the pair can be created or resynchronized, but it will then suspend because of host I/O. To perform these operations (including reverse resync), remove the host where the SCSI-3 Persistent Reservation key is registered, delete the key on the S-VOL, and then create or resynchronized the pair. If you cannot delete the key from the host, contact the HP Technical Support. Restrictions 69

Restrictions
The following restrictions apply when using ESAM in a cluster system:
•
You cannot use ESAM pair volumes for SAN boot.
•
You cannot store OS page files in ESAM pair volumes.
•
For Windows Server® 2008 R2, ESAM does not support Hyper-V function and Cluster Shared
Volumes (CSV) function.
•
If using software with SCSI-2 Reservation, and SCSI-2 Reservation is registered on the P-VOL,
a pair cannot be created or resynchronized if SCSI-3 Persistent Reservation key information
is also registered on the S-VOL.
If SCSI-2 Reservation or SCSI-3 Persistent Reservation key information are not registered on
the P-VOL, but SCSI-3 Persistent Reservation key information is registered on the S-VOL, the
pair can be created or resynchronized, but it will then suspend because of host I/O.
To perform these operations (including reverse resync), remove the host where the SCSI-3
Persistent Reservation key is registered, delete the key on the S-VOL, and then create or
resynchronized the pair. If you cannot delete the key from the host, contact the HP Technical
Support.
