148 TrueCopy for the XP128/XP1024/XP10000/XP12000

CAUTION:

The QUIESCE option of the CSUSPEND command has been disabled by APAR OW15247 or

APAR OW15248. For detailed information on the QUIESCE option of the CSUSPEND command, refer to

either of these APARs. Check with your HP account team before using the CSUSPEND command with the

QUIESCE option to suspend TC390 volume pairs on an XP128/XP1024/XP10000/XP12000 (or other XP

disk array). If the CSUSPEND command with the QUIESCE option is issued to certain volumes (for

example, active SPOOL, PAGE, or CATALOG datasets, or active SYSRES volume), the attached host(s) may

enter a deadlock condition and may require a storage control IML to correct the condition. TC390A does

not support the CSUSPEND/QUIESCE option.

Using PPRC TSO Commands with TrueCopy Asynchronous

For TC390A operations, special switches and parameters are used to control and monitor TC390A pairs

and groups using PPRC commands. This section describes this special use of PPRC TSO commands for

Suspend Pair

CSUSPEND

PPRCOPY

SUSPEND

M-VOL or

R-VOL

Suspends a TC390 pair (or TC390A group).

TC390 supports the optional PRIMARY

parameter. See Caution below on the

QUIESCE parameter. For details on

CSUSPEND for TC390A, see ”

CSUSPEND”

on page 154

.

Delete Pair

(to MCU)

CDELPAIR

PPRCOPY

DELPAIR

M-VOL

Deletes a TC390 pair (or TC390A group)

from the MCU. For details on using CDELPAIR

for TC390A, see ”

CDELPAIR” on page 155

.

Delete Pair

(to RCU)

CRECOVER

PPRCOPY

RECOVER

R-VOL

Deletes a TC390 pair (or TC390A group)

from the RCU. For details on using

CRECOVER for TC390A, see ”

CRECOVER”

on page 155

.

Pair Status

CQUERY/

VOLUME

PPRCOPY

QUERY/

VOLUME

M-VOL or

R-VOL

Displays the TC390 and TC390A pair status

of the volume. TC390 supports the optional

Resume Pair

CESTPAIR

(MODE=

RESYNC)

PPRCOPY

ESTPAIR

M-VOL

Resumes a TC390 pair (or TC390A group),

and sets the TC390 initial copy options and

pair options. TC390 supports the optional

MODE, PACE, and CRIT parameters. For

details on using CESTPAIR/RESYNC for

TC390A, see ”

CESTPAIR
