For example, we would like to add more volumes on one new lcu under MSS1. As the new volumes on MSS1 cannot vary online, how to do it, please advise. Moreover, the new volume on MSS1 is offline, how to run TDMF ? Does it mean that once we run the hyperswap to MSS1 (3390D vol on sub-channel set 1), we can do nothing on new disk ?

Inform Raymond about that.

Please see the following in GDPS/PPRC V3R10 Installation and Customization Guide section "5.15.9 Migrating or adding device pairs in MSS1" < email screen print that section > Action plan: pending feedback from Raymond, next FUP Aug 05 -Imem, Bittile -694235B00 -L50G/CBES -P4S4-15/08/05-03:40 -CT -Imem, Bittile -694235B00 -L50G/CBES -P4S4-15/08/05-04:04 -CC S5> SERVICE GIVEN= 99 SG/99/ Got customer Raymond's feedback Refer your last update, it is really a restriction that we cannot add/migrate any volumes after running hyperswap to site2 on MSS1. If then, it should be a product defect on using MSS1. In fact, after hyperswap to site 2, we cannot prevent any new disk requirement, or disk migration on using TDMF, it is unrealistic and unacceptable on system administration. Anyway, could IBM take it as enhancement on coming release? Action taken: submit following into GDPS Forum According to GDPS/PPRC V3R10 Installation and Customization Guide section "5.15.9 Migrating or adding device pairs in MSS1" it states You must perform the add/migrate process when your primary devices are in Site 1 (that is, when the devices defined in MSS0 are primary). . It is a restriction that customer cannot add/migrate any volumes after running hyperswap to site2 on MSS1. If then, it should be a product limitation on using MSS1. In fact, after hyperswap to site 2, we cannot prevent any new disk requirement, or disk migration, it is unrealistic and unacceptable on system administration. . Anyway, would GDPS let adding/migrating devices possible in MSS1 as enhancement on coming releases ? Action plan: await reply in forum, next FUP Aug 12 -Imem, Bittile -694235B00 -L50G/-------P4S4-15/08/11-06:23 -AT Rec'd advice from GDPS Development Jusid Flenclust that he has passed related information to customer Strun Autil in Feb this year. .
