HP XP P9000 External Storage Access Manager User Guide (AV400-96607, January 2014)

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.
