Hello,
I'm pretty new to this very helpful community, this is my first post, and I will try to be very specific about my problem, because HP support is not very accurate.
I'm working for a hosting company, and we've recently bought a 3Par system that is running fine, but I get a warning yesterday about CPG allocated percentage high (98%) remaining 16GB.
Here are the specs :
* HP_3PAR 7200, 3.1.3 MU1 * 1 cage, with dual controllers : - 8 * 900GB 10K + 4 * 480GB SSD MLC * 1 cage, attached by SAS to the first cage : - 8 * 900GB 10K + 4 * 480GB SSD MLC
Each controller is attached by FC to a virtual connect module, in a single HP c7000 enclosure, without any FC fabric. 4 blades are running ESXi 5.5 in a full vmware featured cluster. The 3Par datastores are reachable through a FCoE emulation provided by the virtualconnect modules.
I've created 2 CPG :
1. CPG_R1_FC : Raid1, availibility cage, device type FC, no limit nor warning enabled on growth 2. CPG_R1_SSD : Raid1, availibility cage, device type SSD, no limit nor warning enabled on growth
I've created and exported 6 vv as well :
cli% showvv ----Rsvd(MB)---- -(MB)-- Id Name Prov Type CopyOf BsId Rd -Detailed_State- Adm Snp Usr VSize 1 .srdata full base --- 1 RW normal 0 0 61440 61440 0 admin full base --- 0 RW normal 0 0 10240 10240 12 VV1_THIN_FC tpvv base --- 12 RW normal 256 0 119808 204800 13 VV2_THIN_FC full base --- 13 RW normal 0 0 204800 204800 14 VV3_THIN_SSD tpvv base --- 14 RW normal 384 0 384000 921600 15 VV4_THIN_FC tpvv base --- 15 RW normal 512 0 427904 614400 16 VV5_THIC_FC full base --- 16 RW normal 0 0 2097152 2097152 17 VV6_THIC_SSD tpvv base --- 17 RW normal 512 0 434176 1043456 ---------------------------------------------------------------------------------- 8 total 1664 0 3739520 5157888
The first problem I have, is about the VV6_THIC_SSD. It has been configured to use the CPG_R1_SSD, but the GUI show this volume as FC volume.
The second problem I have is about the CPG usage, both of them are 98% used, and I don't know to free some capacity. I've converted some VV from full to tpvv, I've deleted a 200GB vv as well, and I've compacted both CPG.
Here is the alerte message : CPG 2 (CPG_R1_SSD) could not grow with its normal grow parameters.-The following parameters were used: createald -wait 0 -cpsd CPG_R1_SSD -t r1 -ha mag -ssz 2 -ss 32 -ch first -p -devtype FC -n tp-2-sd-2 -sz 8192
The HP 3Par management console displays device type SSD for this CPG, this is really strange.
Does somebody here met this kind of issue ?
Cheers, and merry christmas to all.
